Tendons are strong elastic fibers that attach muscles to bones. To a reasonable approximation, they obey Hooke's law. In laboratory tests on a particular tendon, it was found that, when a 0.255 kg object was hung from it, the tendon stretched 1.25 cm Part A Find the force constant of this tendon in N/m Express your answer in newtons per meter. Part B Because of its thickness, the maximum tension this tendon can support without rupturing is 145 N. By how much can the tendon stretch without rupturing, and how much energy is stored in it at that point? Express your answer in centimeters. Part C Express your answer in joules.

Mechanical Properties of Solids

There are three types of matter- solid, liquid and gas. Out of them, solids have a rigid shaped and size. The intermolecular forces of attractions in solids are greatest. Mechanical properties are the physical properties of a material which it shows, when it is provided with certain amount of force or load. These properties are to be kept in mind for various purposes. When a force is applied to an object, the object may or may not get deformed depending upon its elastic property. But every time the object develops a restoring force against the force applied. This is commonly known as stress. If the object changes its dimensions due to the force applied it develops strain ( which is the ratio of change in dimension to the original dimension).
