A hydraulic lift is lifting a car that weighs 15 kN. The area of the piston supporting the car is A, the area of the other piston is a, and the ratio A/a is 104.7. How far must the small piston be pushed down to raise the car a distance of 1.9 cm? [Hint: Consider the work to be done.]Please help, I can not figure this out. thank you
