A hydraulic system is used to lift a 3,000 kg vehicle in an auto garage. Piston A of area 0.8 m² in the hydraulic system is used to lift the platform which the vehicle sits on. This piston can be moved up by applying a downward force on piston B of area 0.05 m² in the hydraulic system. What is the minimum force that must be applied to piston B in order to lift the vehicle ?
- 1,875 N
- 12,225 N
- 1,180 N
- 1,225 N
- 1,250 N
