Example $2$: Shear Strain

Given:

The metal bracket is supported by a rubber isolation pad with dimensions shown. Under a load of $5000$ lbf $,$ the bracket deflects downwald $0\mathrm{.}125$ in$.$

Find:

The average shear stress in the isolation pad

The shear strain in the isolation pad

Soln:

Find the shear stress..

${}_{\text{a}\text{v}\text{e}}=$

Find the shear strain...

$=\frac{2in}{}={0\mathrm{.}125}^{\text{'}\text{'}}$
