A single plate friction clutch has to match with an engine which has a maximum torque (T_{e max}) of 150 N m. (ASSUME UNIFORM WEAR), where:  r_i = 70 mm, β = 1.6

friction material characteristics are:
p_max = 0.2 MPa, µ = 0.4, , find:

a) the clutch torque capacity

b) the value of outer diameter r_o

c) chose a suitable material for the clutch cover pins. If the number of
pins (n_pin) = 3, pin diameter d_pin=4 mm. Take a factor of safety (SF = 8)
