   (a) Fig. 1 shows a rack and pinion system that is attached to two springs
   and a damper. For
   this system, its output will be the displacement of the rack (x). The spring
   constants, damper
   coefficient, mass of the rack as well as the moment of inertia and radius of
   the pinion are
   given in Fig. 1. A motor torque is applied on the pinion (τ) and there is a
   constant force
   acting on the rack (f). Assuming no-slip and zero initial conditions, derive
   and draw out the
   block diagram components of this system.
   (5 marks)
   (b) The values of the variables are given as τ=5Nm and f=1N. Solve for the
   general
   solution of x(t).
   (NOTE: We assume that the robot has zero initial conditions for the entire
   question.)
