3) For the system shown in the figure, the input is the torque T(t) and the outputs are the linear displacements x(t) and the angular displacement θ(t). The equilibrium position corresponds to x 0 0. Note that there is viscous friction between the rack and the surface it slides on. Also, you may treat the small diameter shaft as massless and rigid. mr Clearly state all assumptions to be used for modeling this system. Draw the freebody diagrams. State your...
