Problem

A car lift is designed to raise a

14\,000\,\text{N}

vehicle. The large piston area is

0.35\,\text{m}^2

and the small piston area is

0.020\,\text{m}^2

. For safety, the applied force on the small piston must be

25\%

greater than the theoretical minimum. What force must the operator actually apply? a)

800\,\text{N}

1\,000\,\text{N}

640\,\text{N}

960\,\text{N}
