Mechanical properties of Solids

What happens when the stress applied to the body is increased beyond the maximum value and is removed after some time?

• The body will come back to its original position

• The body will oppose the stress

• The body cannot return to its original position

• The body becomes hot

Air is more elastic than water.

• True

• False

The spring balance does not read properly after its long use, because

• The elasticity of spring increases

• The elasticity decreases

• Its plastic power decreases

• Its plastic power increases

When force is acting parallel to surface then the corresponding stress is known as

• Shear Stress

• Tensile stress

• Compressive stress

• Direct stress
