A tube has an area of 1.0 m² on one end and an area of 0.25 m² on the other. In order for a force of 27N to be created on the 0.25 m² end, what force would the force have to be on the 1.0 m² end?

A hydraulic lift works by applying force to one end of a closed tube to create a stronger force on the other end. In order to lift a car, a hydraulic lift must exert a force equal to the mass of the car. If a car has a weight of 1,375N what force must be applied to the other end if the area of the end lifting the car is 10 m² and the area of the other end is 2 m²?
