2.13 Figure P2.13 shows a disk with moment of inertia that is initially rotating on an axis supported by bearings. No input torque from an external source is applied to the disk. The rotating disk is immersed in a stationary cylinder that is filled with hydraulic fluid. The disk is subjected to friction, modeled using linear viscous friction coefficient b. Derive an equation for the instantaneous rate of energy loss (ie, power dissipated) because of the rotation of the disk in the viscous friction using two methods: (1) use the time derivative of total mechanical energy and (2) use the definition power torque x angular velocity.
