CLMECH-5LD6UK

A hydraulic lift system is used to raise cars in a repair shop. A force is applied to a circular piston of radius $0.12 \space m$. A car is lifted by a circular piston of radius $0.44 \space m$. Ignore the mass of the lifting system.

What minimum force needs to be applied on the smaller piston to lift a $1900 \space kg$ car?
