) A wet multiple-disc clutch with sintered linings is required to transmit 120 Nm of torque at 1000 rev/min. The axial force is created when 6 helical compression springs deflect 5 mm. Each spring has a spring constant k = 142 N/mm. Assuming uniform wear, determine :- (i) the outside and inside diameters if ri = 0.577 ro . (ii) the number of discs required. (iii) the maximum power that can be transmitted

A multi-disc wet clutch is to transmit 120 Nm of torque at 1000
rpm using sintered friction material.
(i) Assuming uniform wear, find the outside and inside diameters
required if ri = 0.577ro.
(ii) What is the power transmitted?
(iii) Using the diameters found in (i), determine the power
transmitted when the clutch is new.

A certain engine develops an output torque of 1800 + 200sin2??
Nm, where ? is the crank angle measured from some datum. This
engine drives a machine which requires a driving torque of 1800 +
300sin?? Nm. The rotating parts have a mass of 100 kg, with a
radius of gyration of 0.25 m. The maximum speed of the rotating
parts is observed to be 250 rev/min. a) Sketch both the driving and
load torque curves on the same axes...
