Question: Pascals Principle/ Hydrualics? I have a bunch of physical science homework that I didnt do last semester so I have to do it now and I dont know any of the math portions so I could really use some help:\n\nA hyraulic lift chair has its seat attached to a piston with an area of 11.2cm(2) yada yada yada the other piston exerts with an area of 4.12 cm(2) person on chair exerts downward force of 219 N what force needs to be exerted on the small piston to ;ift the seat.\n\n7468 list on large piston, wit an area of 28.27cm(2), how much force must be exerted on small piston if it has an area of 1.325cm(2)?

Answer: 1.) The force over the area of the large piston will be equal to the force over the area of the small piston. (F1/A1 = F2/A2)\n\nSo:\nF1 = 219N\nA1 = 11.2 cm^2\nF2 = x\nA2 = 4.12 cm^2\n\n219 / 11.2 = x / 4.12\nx = 19.5536 * 4.12\nx = 80.56 N\n\nArmed with that, you should be able to do #2.
