Force necessary to support mass on Hydraulic Jack??? 1. The problem statement, all variables and given/known data Piston 1 in the figure has a diameter of 1.31 cm. distance of 2 in Piston 2 has a diameter of 7.91 cm. distance of 10 in In the absence of friction, determine the force F, necessary to support an object with a mass of 904 kg placed on piston 2. (Neglect the height difference between the bottom of the two pistons, and assume that the pistons are massless). 2. Relevant equations F1*d1 = Fp*d2, where d1 is the moment arm of F1, and d2 is the moment arm of Fp. 3. The attempt at a solution Fp = (F1*d1)/d2 (904)(9.81)/(pi)(0.003955)^2= F/(pi)(0.00655)^2 F=242.98 N which was incorrect. anyone have an idea of what I should do and what equation to use? Thanks!
