A227 pound compressor is supported by four legs that contact the floor of a machine shop. at the bottom of each leg there is a circular pad formed from a synthetic material to dampen vibration. the synthetic material will support up to a maximum pressure of 42 psi before deforming. what is the minimum diameter to avoid deforming the material?

Explanation:
Data provided in the question:
Weight of the compressor, W = 227 pound
Number of legs = 4
Maximum pressure = 42 psi
Now,
Let F be the force taken by the legs
Therefore,
W = 4F
or
227 pound = 4F
or
F = 56.75 pounds
Also,
Force = Pressure × Area
or
56.75 pounds = 42 psi × πr² [ r is the diameter of one leg]
or
r² = 0.4301
or
r = 0.656
therefore,
diameter = 2r = 2 × 0.656
= 1.312 in
