The Scrambler

For our project we made a wooden car that would carry our egg at least 5 meters. Our car was purple, pink and contained glitter. Miranda painted the car so the top was purple with silver glitter and the sides were pink. We also put “wings” on the side which were light purple and gave the car more character. To give the car a rider we also added a littlest pet shop dog which was glued to the front. I would have to say our car was the cutest. For our car we decided to make it a rubber band car since that would give it the most mechanical and potential energy. The rubber bands were to act as our…

Biomechanics of Surfing

Understanding the fundamental relationships in mechanics, helps form a foundation for the analysis of human movement in surfing. The main principle or law of motion I am going to look into is Newton’s Law of Action and Reaction. This law of motion is mainly applied when paddling. It helps me understand how the application of force to my arm and hand determines the speed and movement of my surfboard and this allows such movement to become more efficient. The most important skill in surfing is learning the correct paddling technique. A good paddler catches plenty of waves while poor paddlers spend most of their time and energy missing them. I am now going to present my 1st video to you,…

Excessive Force

Being a Police officer is dangers work, every day and every night they are put in harms way and at times have to use bruitily aka excessive force when they fill the needed. Yet there has been cases where the authorities have used extreme force where it was not needed, things of that nature should be brought to our attention and addressed apparently. In my eyes police brutality is a major problem all over the United States. Me being a black male I really think racism comes into play during a cases of police brutality, for example Twenty-one-year-old Patrick Lee was allegedly “acting strangely” outside a nightclub in 2005 when he was tasered by police 19 times, sprayed with pepper…

Simple Machines

Simple machines are extremely important to everyday life. They make stuff that is normally difficult a piece of cake. There are several types of simple machines. The first simple machine is a lever. A lever consists of a fulcrum, load, and effort force. A fulcrum is the support. The placing of the fulcrum changes the amount of force and distance it will take in order to move an object. The load is the applied force. The effort force is the force applied on the opposite side of the load. Levers can be placed in three classes. The 1st class levers are objects like pliers where the fulcrum is at the center of the lever. The 2nd class of levers are…

Force Field Analysis

The planning process in the business by use of the force field analysis seeks to look at the forces that come against or for a decision. The tool helps in planning about strengthening those forces that support a certain decision and reject or reduce the support for those that oppose a decision. It is widely used in the planning and decision making process within an organization to bring corporate changes. (http://www. ifm. eng. cam. ac. uk/dstools/represent/forcef. html) The theory argues that the change in the force field analysis has a characteristic phenomena of been in an imbalance state between the various driving forces. These could be changing market situations, new personnel/management or new technology above other fundamental factors in the…

Donor Services

1) Joanna’s diagnosis was that the department was fairly inefficient. There was a large discrepancy in between work load distribution, with mounds of paper work piling up with Magdalena and some of the newer workers, while the clique had time to sit around, gossip and not do work. Another thing was that Sam and Jose never looked at any of the work done by the department. They only reviewed the case histories. The employees couldn’t really explain why their jobs were done and only knew a little about the department and their specific job. Morale was also low, and this is another cause for inefficiency. 2) I think she should recommend that the work load should be more evenly distributed…

Problems of Working Women

The financial demands on the Indian families are becoming fiercer by day. The sky rocketing cost of living, increasing expenses on education of children, increasing cost of housing properties in India force every family in India to look for ways and means of increasing the household income. As a result, women in India who were mostly known as homemakers are forced to go for jobs and take up even careers that were considered only suitable for men such as working in night shifts in call centers or BPOs. They are left with no option but to fend for their families in all possible ways. Working women in India are faced with lot more challenges than their counterparts in the other…

Stress Strain Relationship

The unique relationship between stress (intensity of force) and strain (measurement of deformation) is evident. The external forces that act on the body impose loads that affect the internal structures of the body. In biomechanics, the understanding of mechanical properties internal forces is important for preventing injury and evaluating the causes of injury. It starts with mechanical stress, the internal force divided by the cross-sectional area of the surface on which the internal force acts. The three principle stresses are tension, compression, shear in biomechanics it’s known as the three basic methods of loading. Tension involves pulling the structure, compression involves a stress that compacts the structure and shear involves pushing the structure eccentrically. Tensile stress is produced when an…

Direct Shear Box Test

Introduction Shear strength is the property that enables a material to remain in equilibrium when its surface is not level. (Smith, 2006) The direct shear test is used to determine the shear strength of soils on a predetermined failure surface. This test is used to measure the shearing resistance, undrained shear strength, and dilative and contractive tendencies in soils. (Fratta et al, 2007) The results can then be used to determine the allowable bearing capacity of foundations and stability of retaining walls, cuttings and embankments. Objective To determine the angle of shearing resistance of a sample of sand; the test may be carried out either dry or fully saturated but not anywhere in between. Apparatus * Motorised shear box *…

Projectile Motion

I. Introduction In this lab the main focus was projectile motion. A projectile is an object flying through the air that is only under the force of gravity (neglecting air resistance). A projectile moves both horizontally and vertically, which creates a parabolic flight path. In vertical projectile motion there is a constant velocity since there are no forces in the horizontal direction (neglecting drag due to air resistance). Consequently, there is no acceleration in horizontal projectile motion. In vertical projectile motion gravity is acting on the projectile, which means that the acceleration in vertical projectile motion is equal to gravity’s acceleration (9.8m/s2). Some equations for projectile motion are the three kinematic equations, the equation for Vx (Vx = ∆x/∆t), and…

Torque: Second Condition of Equilibrium

A torque is an influence, which tends to change the rotational motion of an object. One way to quantify a torque is force applied times the lever arm. In this experiment we consider the systems in equilibrium and its applications and how the forces acting on the system affect torque. To serve as a guide there are objectives set in performing this experiment. First objective is by the second condition applied to the systems of equilibrium and the second objective is to ponder second condition of equilibrium’s use and importance. MATERIALS AND METHODS Setting up the apparatus given with the following materials: Phywe model balance, Pasco Scientific Mass and Hanger Set (ME-8967 & ME-9348), Meterstick, Protactor, Weight Pans and Spring…

Vacations: Psychology and Family

Picture yourself sitting on the beach. It’s a warm sunny day and the sun is beating down on you, warming every inch of your body. You have forgotten every itsy bitsy, as well as mega-problem back at home, your mind has been cleared blank from stress, and all you can think about is how amazing it feels to be lying on the beach doing nothing. People every year miss out on going on vacations. And yet, “getting away from the everyday grind,” for just a few days can set your mind free from all problems. Vacationing, then, is a catharsis. It improves one’s mental health, revamps relationships, helps people to become more productive, and it helps some find creative inspiration,…

War Is a Force That Gives Us Meaning

The book “War Is a Force That Gives Us Meaning” by Chris Hedges provides in-depth discussion of the appeal and pull of war on national actions and attitude of people towards the war. The author highlights fifteen years of experience and reports through his own prism the very nature of the war, its causes and terrible consequences such as numerous deaths, hunger, cataclysms, etc. Moreover, Hedges discusses physical and moral devastation the war leaves. The author claims that war should be considered a deadly addiction or a drug which offers intoxication. He argues that war is meaningless and in reality war is only the basest form of aggression. One interesting moment is that the author argues that the war has…

Newtons Laws Relating to Car Safety Devices

Ever since cars were invented in the early 20th century, there have been road fatalities. Advances in car safety technology have seen a diminishing exponential curve in casualties suffered on the road. The first invention was the seatbelt, by George Cayley in the late 1900s. The next major advance was with the airbag, by John Hetrick in 1952. A patent for the design was marketed for automobiles in 1967. The combination of all safety devices located in cars contribute to the wellbeing of the driverThe idea of a seat belt is simple, but it harnesses technology that shows a lot of ingenuity. A seatbelt is designed to keep one fastened in their seat in the event of an abrupt stop….

The diverse nature of the company leads to many different customer demands. The oil refineries have two types of customers….

Case analysis: Deloitte & Touche

In Deloitte & Touche, women had accounted for almost half of all new hires throughout the 1980s, yet by 1991, of the 50 candidates being nominated for partnership on that year, only four were women. There was serious imbalance of male and female gender in the workforce despite steps to ensure that the firm would be hiring women during the 1980s. Moreover, the high turnover of women leaving was accruing huge expenses for the firm . In this paper, I will first discuss the challenges faced in the organization and the reasons why the management saw a need for an organization change. Next, I will argue that the current situation favors the change process and despite the possible restraining forces;…

The truest evil in I’m Not Scared is poverty

The novel “I’m Not Scared” illustrates the harsh, brutal and dangerous lives of people living in Acqua Traverse. Author Niccolo Ammaniti reveals how people in Acqua Traverse overcome their strongest adversary, poverty. Individuals who are poverty-stricken are motivated to act against their moral code to achieve a higher standard of living. Some will overcome this malicious force by acting against their moral conscience. In many circumstances, humans are often given the choice to decide but in “I’m Not Scared,” poverty has sparked the ambitions of many in Acqua Traverse to become immoral. Evidently, poverty victimizes everyone in Acqua Traverse, “a place forgotten by God and men. ” Poverty portrayed in Acqua Traverse is one having insufficient materials or one lacking…

Single Pulley

Aim: For this assignment I intend to investigate about pulley. The main aim of my project is to investigate pulley. I will start off with a few lines about what the pulley is and what is used for; Pulley is used to lift objects. A pulley consists of a grooved wheel and a rope threaded around the disk. The disk of the pulley rotates as the rope moves over it. Pulleys are used for lifting by attaching one end of the rope to the objects, threading the rope through the pulley and pulling on the other end of the rope. A single pulley reverses the direction of a force. When two or more pulleys are connected together, they permit a…

Fear motivation

If you remember the movie Office Space, you might remember this great line where Peter (the guy trying to get fired) says “If you motivate people by fear, they will do just enough to get by and not get fired. This is the saddest of all motivational factors. Fear of rejection, fear of loss of respect, loss of money and country club status. It’s related to the above motivations, but from a different perspective. People who are motivated by fear are motivated from a position of having made it and are afraid of losing it. Its real difference is in its motivational power. Fear can be a strong motivator. . It’s one of the oldest forms of motivation and one…

Bayfield Mud Company

The Bayfield Mud Company has had some problems with their 50 pound bags of treating agents. They sent shipped some bags to Wet Land Drilling, Inc. that were found to be short-weight by approximately 5%. Wet Land first did their own research on how many bags were short and by how much. They randomly sampled 50 bags and found the average net weight to be 47.51 pounds. Wet Land then contacted Bayfield Mud about the situation. Bayfield gave a 5% credit to Wed-Land for the mistakes. But We Land not completely satisfied with the credit because the errors in the weight of the bags could impact their operations. Wet Land informed Bayfield Mud that if something like this happened again,…

Porter Five Forces

What is Porter’s 5 Forces analysis? What are the main aspects of Porter’s 5 Forces analysis? How to write Good Porter’s 5 Forces analysis of a company? Where to find information for Porter’s 5 Forces analysis? Porter’s Five Forces Examples; Reports on Different Companies Introduction There is continuing interest in the study of the forces that impact on an organisation, particularly those that can be harnessed to provide competitive advantage. The ideas and models which emerged during the period from 1979 to the mid-1980s (Porter, 1998) were based on the idea that competitive advantage came from the ability to earn a return on investment that was better than the average for the industry sector (Thurlby, 1998). As Porter’s 5 Forces…

Bayfield Mud Company

1. As Wet-Land Drilling, Inc. had filed a complaint that the bags it received from Bayfield were short-weight by about 5%, they had to determine the cause of the discrepancy. They discovered through checking 50 of the bags that they only had an average net weight of 47.51 pounds. In order to identify the errors that had occurred in the operation, and why the weight has become inconsistent, Bayfield’s quality managers may consider using Statistical Process Control (SPC). As mentioned, past shipments had bags that averaged at 50 pounds, which will be the desired mean, X=50, and that had an acceptable standard deviation of 1.2, which will be the desired = 1.2. x = σn=1.26=0.4899 At a confidence interval of…

Projectile Motion Lab Report

The purpose of Lab Assignment 1 was to analyze projectile motion. In doing so, we determined the initial velocity of the ball shot horizontally from the spring loaded projectile launcher. Also, we verified the angle at which the projection of the ball would produce a maximum range. Lastly, we predicted the range that a ball would travel at a certain angle, theta. Projectile motion is the motion of objects that are initially launched, or projected, and then continue moving with only the force of gravity acting upon it. The forces involved in projectile motion are the initial velocity of the projected object at a certain angle and gravity acting downward on the object. The vector nature of forces can be…

Simple Harmonic Motion Lab Report

Simple harmonic motion is the motion of a mass on a spring when it is subject to the linear elastic restoring force given by Hooke’s Law. In this lab, we will observe simple harmonic motion by studying masses on springs. In the first part of this lab, you will determine the period, T, of the spring by observing one sliding mass that is attached to two springs with the spring constant k, and attached to a hanging mass by a string and a pulley. The next part, you will determine the period, T, of oscillation caused by two springs attached to either side of a sliding mass. By knowing the velocity in the second part, you can find kinetic energy…

Center of gravity

The point in a body or system of bodies at which the whole mass may be considered as concentrated. When an object’s weight is distributed uniformly, the center of gravity lies at its geometrical center. For irregular shaped objects, the center of gravity is near to the concentration of its mass. Equation: Where: X= center of gravity xi= distance of the objects from fulcrum or arbitrary axis mi= mass of the object Sample Problems 1.) Suppose your lab partner has a height of 173cm and a weight of 715N. You can determine the position of his center of gravity by having him stretched out on a uniform board supported by one end by a scale. If the board’s weight is…

Acceleration due to gravity

The acceleration due to gravity, g, was determined by dropping a metal bearing and measuring the free-fall time with a pendulum of known period. The measured value is 9.706 m/s2 with a standard deviation of 0.0317, which does not fall within the range of known terrestrial values. Centrifugal forces and altitude variations cannot account for the discrepancy. The calculation is very sensitive to the measured drop time, making it the likely source of error. (Short, sweet and to the point. I give the result, method and comment on its agreement or validity.) Theory (First, some background. Be sure to cover any non-numerical aspects of the theory that you wish to address. ) The acceleration due to gravity is the acceleration…

Why Less homework is better

Just The Right Amount Of Homework Did you ever think that the pressure from too much homework can cause health problems such as anxiety, and uneasy sleeping? Or that homework fuels the cheating epidemic? Well it does. Homework was originally meant to be a review of what was learned earlier that day in class. But, now at days students are coming home with more and more unnecessary busy work. Some of the down sides of too much homework is that it destroys family life and social structure, because it keeps the child in their room for hours working. Also, the stress of too much after school work can really take a toll on student’s mental health. Nevertheless, homework can be…

Forces for Change

It is important for organizations to be open to change and know how to deal with it. Many organizations fail to recognize change causing the organization to suffer and sometimes come to an end. There are six forces that stimulate change in an organization, nature of the workforce, technology, economic shock, competition, social trends, and world politics. The consequences of these economic shocks are bankruptcy, elimination and sometimes acquisition of organizations causing many employees to lose their jobs (Robbins & Judge, Chapter 18, 2011). Increased environmental awareness, liberalization of attitudes toward gay, lesbian, and transgender employees, and more multitasking and connectivity are examples of social trends, another force that stimulates change (Robbins & Judge, Chapter 18, 2011). The last force…

Water Bottle Rockets

Introduction A water bottle rocket is essentially that; a bottle modified in the image of a rocket then filled with a select amount of water that is pressurised and launched into the air due to the forces pushing the rocket upwards from the launcher. When the completed water bottle rocket is sitting on the launcher, the force of the surface of the launcher pushes the rocket up whilst gravity drags it down. As the fluid inside the rocket is pressurized, the forces become unbalanced and release the clamps that are holding back the rocket. The fluid will then be expelled through the small opening at the bottom of the rocket (the bottles nozzle) at a fast rate in one direction…
