PHY100 Writing 1 - Assignment ExampleChanges in energy occur to the synthetic rubber band when it is opened (application of force) and when it is in unscratched state.Hookes Low potentiometer be used to demonstrate the changes that take place in a rubber band when it is stretched. Hookes law states that the amount of force applied to an elastic end is proportional to the amount of deformation (stretch or compression) that the object undergoes (Breithaupt, 77). This is why when more force is applied on a rubber band, the stretch increases and when a gnomish force is applied, there is little stretch. This principle can be presented in the following equation where F represents the applied force, k represent the force unalterable of the rubber band and x is the length of the stretch recorded. In the equation below, the force applied is proportional to the amount of deformation on the rubber.Despite the occurrence that a rubber band is elastic and can stretch when more force is app lied, the rubber band only stretches up to a certain limit. Robert Hooke withal noted that elastic objects stretches until they reach elastic limit also referred to as yield limit. Beyond this point, the rubber band exhibit plastic deformation and can no longer return to their original shape when the stretch force is removed. Plastic deformation occurs on the rubber band because beyond maximum stretch force, application of extra force results into breaking of limited number of atomic bonds holding together rubber band molecules (Fan & Zhu, 28). This explains why certain parts of the rubber band stretched more than the other parts. These parts that stretched more the other parts must have underwent plastic
