POISSON’S RATIO Let us assume If a body is subjected to a load ( Tensile), Due to this load the dimension of this body changes. its length increased while the area of the body decreased. The Ratio of this change in the length to the original length is known as Linear or Primary Strain and …

Stress and Strain in a bar due to its self-weight A bar of length metre and area A is fixed at one end. Let the density of material be ρ . Let us consider a very small shaded strip of bar ABCD of thickness at a distance y from the bottom end as shown in …
A force exerted on a body can cause a change in either the shape or the motion of the body. The unit of force is the newton, N. The three main types of mechanical force that can act on a body which change the shape of the body are as follows: Tensile Force Compressive Force …
