Question
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 a larger piston of cross-sectional area A (the figure). If the piston diameters are 2.85 cm and 52.2 cm, what force magnitude on the small piston will balance a 14.7 kN force on the large piston?

If the piston diameters are 2.85 cm and 52.2 cm, what force magnitude on the small piston will balance a 14.7 kN force on the large piston?Explanation / Answer
Apply F/A = F/A
14700/(pi)(.261)^2 = F/(pi)(.01425)^2
F = 43.8 N
