Consider the continuous rolling mill depicted in Fig.3.48. Suppose that the motion of the adjustable roller has a damping coefficient b, and that the force exerted by the rolled material on the adjustable roller is proportional to the material's change in thickness: F= c(T-x) Suppose further that the DC motor has a torque constant K, and a back-emf constant K₂, and that the rack-and-pinion has effective radius of R. (a) What are the inputs to this system? The output? (b) Without neglecting the effects of gravity on the adjustable roller, draw a block diagram of the system that explicitly shows the follow- ing quantities: Vç(s), lo (s), F (s) (the force the motor exerts on the adjustable roller), and X(s). (c) Simplify your block diagram as much as possible while still identifying output and each input separately.
