A centrifugal clutch has two rotating contact masses of 0.25 kg. These are able to move in guides attached to the input shaft and are held by springs of stiff ness 8 kN m^-1
. The initial clearance between the masses and the internal surface of a drum on the output shaft is 5 mm. The inner diameter of the drum is 300 mm and the distance from the centre of rotation to the centre of gravity of the masses is 135 mm. The coeffi cient of friction between the masses and the drum is 0.35. Determine

the torque and power transmitted at a speed of 1000 rpm.
