Problem
In an industrial hydraulic press the small piston has cross-sectional area 5.0cm2 and the large piston has area 200cm2. A metal block of weight 16kN is to be lifted.
(i) Calculate the minimum force that must be applied to the small piston to just lift the block.
(ii) If the area of the large piston were reduced to 100cm2 while the small piston area remained unchanged, determine the new force required on the small piston.
(iii) For the original piston areas, find the pressure transmitted through the fluid when the block is just about to rise.
