Bending of Beam Lab Report

1. Objective: The objective of this experiment is to demonstrate the bending of a bean when loaded at the center of its length and examine its deflection when positioned in two different ways, when the flat side of the beam is support and when the thin side is supported. In addition, try to find linear relationship between the load applied and the deflection of the beam and comparing the experimental deflection with the theoretical deflection. If the load is applied at the mid- length a=b=L/2 then mid span deflection is: δ = PL3/(48EI). Where P is the applied force, L is the length of beam, E is the modulus of elasticity of aluminum, and I is the moment of Inertia….

Pulse Rate

The purpose of this practical is to investigate how the pulse rate of humans changes when they exercise. Someone who is physically fit can supply their muscles with enough blood, carrying glucose and oxygen, for an activity at a lower heart and breathing rate. The fitter you are the lower your resting heart rate. You and your classmates will be the humans investigated. SAFETY: If you know you have any condition that affects you doing exercise, please make sure your teacher knows before you start the investigation. In the investigation you are going to measure and record your pulse rate, before and after doing some physical activity. Work in pairs and decide who will be the ‘exerciser’ and who will…
