Question

the volume stress is equal to change in

Answer 1

Compression will be acting on the rod that is pushed by opposite and equal forces at its two ends. This form of stress is termed as compressive stress. Bulk Stress or Volume Stress: When the volume of body changes due to the stress it is termed as Volume stress. Compression will be acting on the rod that is pushed by opposite and equal forces at its two ends. This form of stress is termed as compressive stress. Bulk Stress or Volume Stress: When the volume of body changes due to the stress it is termed as Volume stress.

Answer 2

Answer:

The volume stress is equal to change in pressure.

Explanation:

Volume stress is also known as Bulk stress.

We know that,

• The change in magnitude of force in a unit area is known as volume stress.

        i.e., Volume stress $=$ Magnitude of force /Area.

We also know that,

• The product of change in pressure and area is force.

        i.e., Force $=$ Change in pressure x Area.

Thus, on substituting :

Volume stress $=$ (Change in pressure x Area)/ Area

                        $=$ Change in pressure.

Therefore, the volume stress (or bulk stress) is equal to change in pressure.
