Design a muff coupling to connect two shafts transmitting a 40kW at 120r.p.m. The permissible shear and crushing stress for shaft and key material are 30MPA and 80MPA respectively. The material of muff is cast iron with permissible shear stress 15MPA. Assume the maximum torque transmitted is 25% greater than the mean torque.

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.
