(a) Suggest suitable applications for EACH of the responses listed below. i. Undamped response ii. Underdamped response iii. Critically damped response iv. Overdamped response (b) Figure 2.1 shows a rotational mechanical system with an input torque, T(t) that produces an angular displacement of e(t). . i. Derive the transfer function of the given system, o(s)/T(S). ii. Based on the system shown in Figure 2.1, solve the values of J and D to yield 20% overshoot and a settling time at 2% error band of 2 seconds. T(t) Olt) 0000cco ண J Hi HHHH K = 5 N-m/rad D Figure 2.1 Rotational mechanical systemſ.
