Question

Draw and write shear strain equation

Answer 1

`\phi =(\Delta L)/(h)`

Step-by-step explanation:

Normal strain :

It is the ratio of deformation to the original dimension.Normal strain occurs due to longitudinal force.

Normal strain = ΔL/L

Shear strain:

It is the ratio of deformation to perpendicular dimension.Shear strain occurs due to tangential force.

From the second diagram:

`tan\phi =(\Delta L)/(h)`

if angle Φ is small then we can write

`tan\phi =\phi`

So

`\phi =(\Delta L)/(h)`

This is the shear strain equation.
