In your job as a mechanical engineer you are designing aflywheel and clutch-plate system. DiskA is made of a lighter material than disk B, and the moment of inertia ofdisk A about the shaft is one-third that of disk B. The moment ofinertia of the shaft is negligible. With the clutch disconnected, A isbrought up to an angular speed v0; B is initially at rest. The acceleratingtorque is then removed from A, and A is coupled to B. (Ignorebearing friction.) The design specifications allow for a maximum of2400 J of thermal energy to be developed when the connection ismade. What can be the maximum value of the original kinetic energyof disk A so as not to exceedthe maximum allowed value of the thermalenergy?

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.
