A) find the linearized equation(s) of motion of the system. b) determine the transfer function from the input force f(t) to the displacement x(t) of the mass m. c) find the complete response x(t) of the piston mass m when f(t) is a unit step input force. d) find the steady-state angular displacement θss of the lever aob from the vertical equilibrium due to the application of the unit step input force f(t).
