Question

Only need help for PART B. Thank you.

The schematic diagram of a motor-load system is shown in Fig. 4P-19. The following parameters and variables are defined: Tm(t) is the motor torque; omega m(t) the motor velocity; theta m(t) the motor displacement; omega L(t), the load velocity; theta L(t) the load displacement; K, the torsional spring constant; Jm. the motor inertia; Bm, the motor viscous-friction coefficient; and BL, the load viscous-friction coefficient. Write the torque equations of the system. Find the transfer functions Theta L(S)/Tm(S) and Theta m(s)/Tm(s). Find the characteristic equation of the system. Let Tm(t) = Tm, be a constant applied torque; show that omega m = omega L = constant in the steady state. Find the steady-state speeds omega m and omega L. Repeat part (d) when the value of JL is doubled, but Jm stays the same.
