Clutches, Brakes, Couplings, and Flywheels

The clutch is described as a machine element used to connect or disconnect two shafts together to transmit torque or power. The clutch works on the principles of friction. The clutch is commonly used in automobiles to transfer power from the driving shaft to the driven shaft.

Question

Determine the time required to accelerate a
countershaft of rotating mass 520 kg and
radius of gyration 150 mm to the full speed of
360 rpm from rest through a single clutch. The
internal and external radii are 120 mm and
180 mm. Take friction coefficient as 0.3 and
the spring force (W) as 660 N. Assume that
only one side of clutch is effective.
