Discussion and Review Whenever a body slides along another body a resisting force is called into play that is known as friction. This is a very important force and serves many useful purposes. A person could not walk without friction, nor could a car propel itself along a highway without the friction between the tires and the road surface. On the other hand, friction is very wasteful. It reduces the efficiency of machines because work must be done to overcome…...

Frictional loss in pipe

Abstract The main aim of this experiment was to show how the friction factor varies with Reynolds number by manipulating the flow rate of the fluid in a pipe. The main principle used in the experiment was the Bernoulli’s equation, taking major head losses into account. These major head losses were normally due to wall friction in the pipe and viscous forces between layers in a fluid. Generally the results obtain from the experiment do agree with the theoretical prediction…...

A World Without Friction

Although friction may seem like a minor issue, its absence would chance life as we know it. There would be many negative effects of this like not being able to gain traction on any surface and your ipods earplugs always falling out. Also, there would be many positive effects, such as eliminating the need for coolant in engines and lubricant in machines. Moreover, the absence of friction would be both bad and good. Without friction, many obvious things which we…...

Biomechanical Principles In Basketball

Basketball is a very competitive and popular sport in our society today. The NBA playoffs are going on right now and it has proved to be a very physical and intense post season. This sport takes an extreme amount of talent, coordination, and athletic ability to become a champion. There are a few biomechanical principles that are present during the game of basketball that help these athletes become great. The first biomechanical principle that is present in basketball is Newton’s…...

Reviewing Friction: An Ethnography of Global Connection

Starting with a critical outline of the global patterns and designs in communication, Anna Lowenhaupt Tsing’s seminal work Friction: An Ethnography of Global Connection attempts at a critical examination of the widespread principle of worldwide associations lingering almost everywhere. While Tsing explicates that her work "is not a history of philosophy but rather an ethnography of global connection (Tsing, 2004, p. 1)", she also unravels a tight regard for the seemingly presented connections among the various sections of the society.…...

Importance of Tires Interface

Introduction The research and development in tires is gaining importance these days. Tires play pivotal role in defining the driving dynamics of the car, ride and comfort, fuel economy etc. Tires are the interface between the car and the road and play a significance role in performance of any road going vehicle. Numerous methods have been proposed over the years to understand the mechanism of the tire, the forces generated by the tire and how varying certain parameters affect the…...

The kinetic friction

1. The roughness of the surface of the objects and the plane/track used in the experiment should be in even condition. Meaning the experimenter should check the roughness by touching the surfaces. For instance, in this experiment, a piece of sand paper is wrapped to the wooden block (to investigate the coefficient of the sand paper surface due to the plane surface which is wood). The sand paper should be the one that has not been used before. This is…...

Aim To determine the coefficient of static friction

In this experiment, the coefficient of static friction (s) between a wooden block and granite plane was determined. The coefficient of static friction (s) between the wooden block and granite plane was found to be 0.396 0.0001. The experiment was rather precise as the readings were quite close to the line of best fit when the readings were represented graphically. However, there certainly are sources of error in the experiment. Sources of Error 1. Uncertainty in the triple beam balance…...
