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).

Zoologists have studied the mechanics of locust jumping. When a locust jumps, as depicted in the figure, the resultant force R exerted by the hind legs is the sum of two forces. The first force W acts directly downward to support the locust's weight, which is about 0.02 newton. The second force F is for the takeoff; its magnitude is about 0.29 newton, and the direction makes an angle of 55° with the horizontal. W 55° Find the magnitude of the resultant force R = F + W.
