In this problem, you will derive a (very simple) model of a car drive-train. The drive-shaft and wheel have inertia J1 and J2, respectively. The drive-shaft and wheel are connected by a flexible linkage with stiffness K. The wheel has friction with the road with coefficient B. a) Find the transfer function G1(s) from drive-shaft angle 1(s)=L[1(t)] to wheel angle 2(s)=L[2(t)]. b) Find the transfer function G2(s) from the engine torque T(s)=L[(t)] to the wheel angle 2(s)=L[2(t)] c) The wheel speed (t)=2(t) is the derivative of the wheel angle 2(t). How is the transfer function G3(s) from T(s)=L[(t)] to the wheel speed (s)=L[2(t)] related to the transfer function G2(s) from the previous part
