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.

Two cars, one with and one without ABS, are stopping from the speed v0 = 100 km/h by full braking. The first without ABS by blocking the wheels, i.e. sliding (’kinetic friction’), the second with ABS with still rolling wheels (ideal ’limiting static friction’ assumed).
