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).

Your biceps muscle is attached to your elbow by the distal biceps tendon. An average adults tendon has a 6 mm by 3 mm rectangular cross-section and is 63 mm in length. A tendon has a Young’s modulus of 1.5x10^9 N/m^2. How much work must be done to stretch the length of the distal biceps tendon by 10%? Assume that the tendon is a linearly elastic material and that stretching does not alter it’s cross-section.
