A piston of cross-sectional area a is used in a hydraulic press to exert a small force of magnitude f on the enclosed liquid. A connecting pipe leads to o a larger piston of cross sectional area A (Fig. 14-53). (a) What force magnitude F will the larger piston sustain without moving? (b) If the piston diameters are 3.50 cm and 60.0 cm, what force magnitude on the large piston will balance a 20.0 N force on the small piston?

Explanation

(a) F = (A/a) f, (b) `5.9 xx 10^(3) N`
