1. A hydraulic press has a diameter ration between the two pistons of 8:1. The diameter of the larger piston is 600 mm and it is required to support a mass 3500 kg The press is filled with hydraulic fluid of specific gravity 0 8. Calculate the force required on the smaller piston to provide the required force (a) when the two pistons are level (b) when the smaller piston is 2.6 m below the larger piston.
