1. The problem statement, all variables and given/known data A hydraulic lift has two connected pistons with cross-sectional areas 15 cm2 and 460 cm2. It is filled with oil of density 560 kg/m3. 2. Relevant equations a)What mass must be placed on the small piston to support a car of mass 1100 kg at equal fluid levels? A:35.86 kg b)With the lift in balance with equal fluid levels, a person of mass 70 kg gets into the car. What is the equilibrium height difference in the fluid levels in the pistons? A:2.72 m c) How much did the height of the car drop when the person got in the car? 3. The attempt at a solution Take the difference in height when its the only the car, then find difference in height of car + guy. Subtract those two. But its not working.
