type (indicating the angle between each of the gauges), construct a Mohr's Strain
Circle overleaf. You should assume that gauge A is aligned along the x-axis.
Using the Mohr's Strain Circle calculate the:

HW12
A multiple-disc clutch has five plates having four pairs of active friction surfaces. If
the intensity of pressure is not to exceed 0.127 N/mm², find the power transmitted at
500 r.p.m. The outer and inner radii of friction surfaces are 125 mm and 75 mm
respectively. Assume uniform wear and take the coefficient of friction = 0.3.
