In your job as a mechanical engineer you are designing a flywheel and clutch-plate system like the one in (Figure 1). Disk A is made of a lighter material than disk B, and the moment of inertia of disk A about the shaft is one-third that of disk B. The moment of inertia of the shaft is negligible. With the clutch disconnected, A is brought up to an angular speed wo; B is initially at rest. The accelerating torque is then removed from A, and A is coupled to B. (Ignore bearing friction.) The design specifications allow for a maximum of 3100 J of thermal energy to be developed when the connection is made. Part A What can be the maximum value of the original kinetic energy of disk A so as not to exceed the maximum allowed value of the thermal energy? Express your answer with the appropriate units. KA = Value ? Units Figure BEFORE AFTER 1 of 1 Forces Fand-Fare along the axis of rotation, and thus exert no torque about this axis on either disk. 1+18 Submit Request Answer Provide Feedback Next >
