Example The diameters of cylindrical pistons A and B are 3 cm 20 cm, respectively. The faces of the pistons are at the same elevation, and the intervening passages are filled with an incompressible hydraulic oil. A force P of 100 N is applied at the end of the lever, as shown in the Figure. What weight W can the hydraulic jack support? -80 cm- EN 20 cm -3cm Measurements in cm 20 cm- 20
