Question

(3) As shown in Fig.3-3, the effective areas of the piston on the cap side and head side are A Az-50 cm2 respectively. If the supply flow rate q 40 L/min, oil pressure p 2MPa, and friction, flow resistance and leakage are all neglected, find the maximum possible thrust force the piston can produce and the velocity of the piston under the following conditions: The solenoid of the directional valve is not energized (power off) (5 points) =100 cm2, 2 The solenoid is energized (power on) (5 points) A1 A2 P.q Fig.3-3
