2- Consider the hydraulic system shown below, with flow pump g;(t). {a) [10 marks] Find the transfer function E'\"g (b) [5 marks] Sketch (by hand) the output flow g, (t) if g;(t)= 3u(t), where u(t) is a unit step. The system parameters are Ry = R;=2 [N.s.m>]and C =1 [m*.s%. kg] () [5 marks] For each system parameter R, R;, bnefly descnibe what would happen to the system''s step response 1f we were to double the value of the parameter. %Ll}
