Design a single-plate automobile clutch to transmit a maximum torque of 250 N-m at 2000 rpm.
The outside diameter of the clutch is 250 mm and the clutch is engaged at 55 km/h.
Find:
1. The number of revolutions of the clutch slip during engagement; and
2. Heat to be dissipated by the clutch for each engagement.
The following additional data is available:
Engine torque during engagement = 100 N-m;
Mass of the automobile = 1500 kg;
Diameter of the automobile wheel = 0.7 m;
Moment of inertia of combined engine rotating parts, flywheel, and input side of the clutch = 1
kg-m²;
Gear reduction ratio at differential = 5;
Torque at rear wheels available for accelerating automobile = 175 N-m;
Coefficient of friction for the clutch material = 0.3;
Permissible pressure = 0.13 MPa.
