compressor feet 01

Rubber feet are attached to the legs of the compressor shown for vibration isolation. The dimensions of the feet are:

W = 2 in
L = 3.5 in
H = 0.3 in

When the compressor is running, a dial indicator is used to find that the compressor shakes left and right symmetrically about its equilibrium position with a peak-to-peak movement of 0.013 inches. Assuming the rest of the compressor is rigid, find the average shearing strain in the feet when they are at their peak deflection.
