Cubical Expansion

VOLUMETRIC EXPANSION
Increase in volume of a body on heating is referred to as“VOLUMETRIC EXPANSION ” or “CUBICAL EXPANSION“.
Consider a metallic

Angle of Friction

Angle of friction is defined as the angle made by the resultant of frictional force and the normal reaction with the normal reaction.

Stress

When a body is given external deforming force it undergoes deformation. As the deforming force increases the restoring force also increases. The restoring force per unit area
