Question: 7 find the transfer function g s from the input...

Question details

7. Find the transfer function G (s) from the input torque T(t) to the output angular velocity ω(t)-6(t). θ1(t) I N-m-s/rad T(t) θ2(t) 8 N-m-s/rad kg-m2 kg-m2 3 N-m/rad 9 N-m/rad Hint: This is a multi-degree of freedom system, so youll have to draw the FBD of each rotational mass and thing about winding of the middle spring/damper. Also θ1 and θ2 are not relative coordinates, they are absolute rotations of the masses relative to something fixed (say a wall). Assuming θ2 > θ| > 0, the left damper is twisting, atế1, the left mass twists by θι, the right spring and the right mass twist by θ2, the inner spring twists by θ2-a and the inner damper is twisting at the rate θ2-
