An engine is coupled to a rotating drum by a friction clutch
which has a single plate faced on each side with a ring of friction
material. The inner and outer diameters of the friction faces are
224 mm and 300 mm respectively. The coefficient of friction is 0,3.
Other data available are: axial pressure on plate = 1350 N ; engine
torque is constant at 40,7 N.m inertia of engine equivalent to a
flywheel of mass 20,7 kg; and...
