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

9.
A Proell governor has three fly balls, each of mass 4 kg. The lengths of all the arms are 280
mm and distance of each pivot of arm from the axis of rotation is 35 mm. The length of
extension of lower arms on which each fly ball is attached is 70 mm, and inclined at 25° to the
lower arm. The mass of the sleeve is 50 kg. Knowing that the arms are inclined at 50° to the
axis of rotation and frictional force between spindle and sleeve is 45 N, determine the
maximum and minimum equilibrium speeds of the governor.

Problem 18.2 As part of a school bus safety test program, school buses are being tested for potential roll-over hazards. To test the bus, it is placed on 1000-pound moveable concrete pad that rolls freely without friction. The horizontal motion of the pad is produced by a hydraulic ram which pulls the pad to left. A 5000-pound school bus is placed on the pad as shown in the figure. a) Assuming the bus does not slip on the pad, determine the minimum value of the horizontal acceleration (dv/dt) of the pad in the direction indicated that will cause the bus to tip, in ft/s². b) Determine the force, in lbf, that the ram must apply to the platform to produce the acceleration found in part (a). c) Determine the minimum static coefficient of friction between the tires and the concrete pad that is required to keep the bus from slipping on the moving pad. d = 3 ft h = 4 ft Desired direction of pad motion Hydraulic Ram h Bus Pad Ans: a) 23 ft/s² ≤ |ax| ≤ 25 ft/s² b) 4500 lbf ≤|F| ≤ 4600 lbf c)…
