Consider the rigid-body model of driveline. (a) Compare the system of Problem 6.7 with the rigid-body model and determine  and I. (b) Specify which components have been ignored. (c) Describe what the system of Problem 6.7 is telling you and if it is comparable to what was discussed in Chapter 3.

Problem 6.7

A rigid body model of the driveline is represented as a simplified model in Figure P6.7 by ignoring damping: (a) Derive the equations of motion of the system (note the differential causalities). (b) Find the equation for the angular acceleration  of the wheel (c) Find an expression for the overall gear ratio n that maximizes  (d) Is the result useful?
