[SOLVED] Pascal's Principle help. 1. The problem statement, all variables and given/known data A piston of cross-sectional area a is used in a hydraulic press to exert a small force magnitude f on the enclosed liquid. A connecting pipe leads to a larger piston of cross-sectional area A. 1. What force magnitude F(2) will the larger piston sustain without moving? 2.If the piston diameters are 3.80cm and 53.0cm, what force magnitude on the small piston will balance a 20.0kN force on the large piston? 2. Relevant equations F_1A_1=F_2A_2 3. The attempt at a solution For a i just solved the equation for F_2. so (F_1*A_1)/A_2=F_2 For B i plugged in my numbers where>>> F_2=(20.0kN*pi*.019^2)/pi*.265^2 F_2=1.03*10^2N??? Any help?
