Question

A hydraulic lift has two connected pistons with cross-sectional areas 20.0 cm2 and 590.0 cm2. It is filled with oil of density 630.0 kg/m3. 1) What mass must be placed on the small piston to support a car of mass 1100.0 kg at equal fluid levels? m = 2) With the lift in balance with equal fluid levels, a person of mass 70.0 kg gets into the car. What is the equilibrium height difference in the fluid levels in the pistons? ?h = 3) How much did the height of the car drop when the person got in the car? h =

Explanation / Answer

a ) 1100/590 = M/10 M = 18.664 kg b b) The fluid pressure due to the height difference must match the 70 kg 70*g/590 = ?gh calculate? mm
