tep 1 First option says : The relative amount of deformation of a material, this is called strain not stress.   second option :the relative force resisting deformation of a material due to an external load on the material , this is the young modulus.   fourth option :the amount a material can stretch before it breaks ,it is called elastic limit.   Last option : The amount of energy that can be absorbed by a material before it breaks ,it is called the energy .   third option :the force applied to a material . and also stress is defined as force applied to a material per unit cross sectional area.     Step 2 Hence the correct option is : the force applied to a material .

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).
