A hydraulic press has a ram of 150 mm diameter and plunger of 25 mm diameter. The stroke length of the plunger is 250 mm. The weight lifted by the press is 2000 N and the distance moved by the weight is 1.5 m in 30 min. Determine (a) the force applied on the plunger, (b) number of strokes performed by the plunger and (c) the power required to drive the plunger.
