As a hydraulic cylinder rotates around O, the exposed length L of the piston rod P is controlled by the action of oil pressure in the cylinder. If the cylinder rotates at a constant rate 0- 60 deg/sec and L is decreasing at the constant rate of 150 mm/sec, calculate the magnitudes of the velocity and acceleration A of end B when L-125mm V 375 m 1)

A cylinder is required to life a load of 120 kN in a system. Fluid pressure available is 15 Mpa. What cylinder size is required? A pump supplies oil at 0.0016 m3/s to a 40 mm diameter double acting hydraulic cylinder. If the load is 5000 N (extending and retracting) and the rod diameter is 20 mm, find the; (i) hydraulic pressure during the extending stroke; (ii) piston velocity during the extending stroke; (iii) cylinder kW power during the extending...
