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).

Question

4. You have three blocks of different dimensions as follows b, (400mmx250mm),
b,(400mmx3000mm), b,(400mmx4000mm). Compute the stress carried by each block when
you apply a vertical force of 50N. From this computation or test, how does the area affect the
stress carried by the material?
