i'm having difficulty with part C of this problem.
A hydraulic lift has two connected pistons with cross-sectional
areas 25 cm2 and 430 cm2. It is filled with oil of density 500 kg/m3.
a) What mass must be placed on the small piston to support a car of mass 1300 kg at equal fluid levels? (answer: 75.58kg)
b) With the lift in balance with equal fluid levels, a person of mass 60 kg gets into the car. What is the equilibrium height difference in the fluid levels in the pistons? (Answer= 2.8m)
c) How much did the height of the car drop when the person got in the car? ?
please help. my rationale thus far is that volume is conserved. could anyone direct me in applying the right concept? thanks.
