To lift an automobile of `200 kg.` a hydraulic pump with a larger piston `900cm^(2)` in area is employed. Calculate the force that must be applied to pump a small piston of area `10cm^(2)` to accomplish this task.

To lift an automobile of 2000 kg, a hydraulic pump with a large piston 30 cm square in area is employed. Calculate the force that must be applied to pump a small piston of area 10 square cm to achieve it.

In a hydraulic press, the area of smaller and larger pistons are 5 cm^(2) and 20 cm^(2) , respectively. Calculate the weight which can be raised by larger piston if a force of 100 kgf is applied on smaller piston.

In a hydraulic press, the area of smaller piston is 5 cm ""^(2) . The weight raised by larger piston is 900 kgf if a force of 150 kgf is applied on smaller piston. Calculate the area of larger piston.

A car of mass 1400 kg placed on the platform in a service station has to be lifted up. The area of the press piston to which the platform is 5m^(2) . Determine the force that has to be applied on the piston of pump cylinder having an area of cross section 0*25m^(2) . (Take g = 10 m s^(-2))

In an arrangement similar to a hydraulic lift, the diameters of smaller and larger pistons are 1.0 cm and 3.0 cm respectively. What is the force exerted on the larger piston when a force of 10 N is applied to the smaller piston?
