3 EW) 24. A centrifugal clutch has four blocks which slide radially in a spider keyed to the driving shaft and make contact with the internal cylindrical surface of a drum keyed to the driven shaft. When the clutch is at rest each block is pulled against a stop by a spring so as to leave a radial clearance of 6 mm between the block and the drum. The pull exerted by the spring is then 450 N and the mass centre of the block is 200 mm from the axis of the clutch. If the internal diameter of the drum is 500 mm, the mass of each block is 7 kg, the stiffness of each spring is 35 kN/m and the coefficient of friction between block and drum is 0-3, find the maximum power the clutch can transmit at 500 rev/min.

Power Transmission Elements

It is defined as the energy transfer from one location to another location. The energy will start moving from the energy generation source to the energy applied position to obtain the work output. From this method, a large amount of electric energy moves from the power station to various electrical substations.

24. A centrifugal clutch has four blocks which slide radially in a spider keyed
to the driving shaft and make contact with the internal cylindrical surface of a
drum keyed to the driven shaft. When the clutch is at rest each block is pulled
against a stop by a spring so as to leave a radial clearance of 6 mm between the
block and the drum. The pull exerted by the spring is then 450 N and the mass
centre of the block is 200 mm from the axis of the clutch.
If the internal diameter of the drum is 500 mm, the mass of each block is
7 kg, the stiffness of each spring is 35 kN/m and the coefficient of friction between
block and drum is 0-3, find the maximum power the clutch can transmit at
500 rev/min. (I. Mech. E.)
(Ans.: 51.7 kW)

Problem 8 Another Gear Two disks are connected to one another with a belt as shown. Both disks have mass m but the larger one has radius 4R and the smaller has radius R. The larger disk is powered by a motor that produces a constant torque, To, in the counter- clockwise direction. (a) By using the rotational equivalent of Newton's laws on the larger disk show that the difference in the tension at the top with the tension at the bottom is: Tto - Thot 1 4R (TO - 2m Ra), where a is the linear accleration of the elt. (b) Do the same (find Ttop - Tbot) with the smaller disk. (c) Use your two expressions to find the gular acceleration of the smaller disk. You answer should have m, R, and To in it only. (Careful, the sr aller disk does not have the same angular acceleration as the larger one).
