A hydraulic lift has two connected pistons with cross-sectional areas 20 cm² and 460 cm². It is filled with oil of density 590 kg/m³.

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?

How much did the height of the car drop when the person got in the car? h =

Expert Solution

Here we apply Pascal's law. And we also apply mass conservation.
