In a motor garage, a hydraulic lift is used to lift heavy automobiles such as trucks. The cross-sectional areas of the piston carrying the load and the piston where force is applied are in the ratio 5 : 3. The mass of a truck is 15000 kg.

What is the magnitude of the force applied on the piston to just lift the truck?
