Really need help with this problem. Reposting as I haven't received an answer the first time I asked. I will rate positively if I receive a response. Thank you.

X5.1 Hydraulic Position Control System-For the composite shown below, obtain a block diagram representation with the appropriate transfer function for each block. Then find the overall closed loop transfer function, Y(s) / R(s) www M x(t) CH B Input Pot under Pressure + e Amplifier K es Tachometer Kt y(t) y(t) ML Mechanical Linkages BL Output Pot == All lower case are functions of time: all UPPER CASE are functions of frequency. r = Input potentiometer voltage, Volt by = Output potentiometer voltage, Volt e = error (r-by), Volt K = amplifier gain, Volt/Volt es= solenoid circuit voltage supply, Volt i = solenoid circuit current, Ampere R = solenoid winding resistance, 12 L = inductance from solenoid wire winding, Henry V = tachometer voltage, Volts Kp = solenoid force constant, N/Ampere F = force due to solenoid, N M = mass of solenoid, Kg B = friction coefficient of solenoid damper, N-s/m K = spring constant of solenoid spring, N/m K = spring constant of lever-arm spring, N/m x(t) = lever-arm displacement at A-handle, m xi(t) = lever-arm displacement at B-pilot valve shaft, m y(t) = lever-arm displacement at C-Power piston shaft, m A = cross sectional area of the power piston, m? p = density of hydraulic fluid, kg/m3 ML = mass of load, Kg K+ = tachometer voltage constant, Volts sec/m Other Constants C1 = Constant #1, m / sec C2 = Constant #2, m/N sec a, b = lengths of hydraulic system lever arm, where a
