The plate clutch consists of a flat plate A that slides over the rotating shaft S. The shaft is fixed to the driving plate gear B. If the gear C, which is in mesh with B, is subjected to a torque M, determine the smallest force P, that must be applied via the control arm, to stop the rotation. The coefficient of static friction between the plates A and D is μs. Assume the bearing pressure between A and D to be uniform.

Given:

M = 0.8 N ∙ m

μ s = 0.4

a = 150 mm

b = 200 mm

c = 100 mm

d = 125 mm

e = 150 mm

f = 30 mm
