A) RL sketch by hand is required. For the unity feedback system of Figure P8.3. where G(s) = K(s - 1)(s - 2)/s(s + 1)(s + 2) sketch the root locus and find the following: a. The breakaway b. The j omega-axis crossing c. The range of gain to keep the system stable d. The value of K to yield a stable system with second-order complex poles, with a damping ratio of 0.5
