Integrated Concepts - Suppose we replace the 4.0-kg book of the biceps muscle with an elastic exercise rope that obeys Hooke’s Law. Assume its force constant k=600 N/m. (a) How much is the rope stretched (past equilibrium) to provide the same force as in this example? Assume the rope is held in the hand at the same location as the book. (b) What force is on the biceps muscle if the exercise rope is pulled straight up so that the forearm makes an angle of with the horizontal? Assume the biceps muscle is still perpendicular to the forearm.

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).
