Ans: - Gaixen :-Pressure on piston during extension stroke, P = 1500 psi - Volume How rate, @= logem. - Leakage @ = 1 9pm - Frictional force, fa soolb. (a)-Maximum value of extending force K atoto = F = PxA-F = 15000 9x3 - 500 a fi = 10102.87 lbf... (6) Piston relocity during extension: w2 - v- q-{ = 1001 - 984 A....3..1x9. . 12732 9pm 2) 1.2 12732x0.00379 ...60 X 6.45.18 10 -0.1246 m.s. To power delievered in extension stroke:
