An automobile sack is lifted by a hydraulic jack that consists of two pistons. The large piston is `1 m` in diameter and the small piston is `10 cm` in diameter. If W be the weight of the car, how much smaller a force is needed on the small piston to lift the car?

An automobile back is lifted by a hydraulic jack that consists of two pistons. The large piston is 70 cm in diameter and the small piston is 8 cm in dimater. If W is the weight of the car, how much smaller a force is required on the small piston in order to lift the car ?

A car is to be lifted by a hydraulic jack which consists of two pistons. The large piston is 80 cm in diameter and the smaller piston is 16 cm in diameter. If W is the weight of the car, then how much smaller force is needed on small pistonto lift the car?

A car is lifted by a hydraulic jack that consists of two pistons. The diameter of the larger piston is 2 m and that of the smaller piston is 50 cm. If the force applied on the smaller piston is 240 N, find the weight of the car.

The average mass that must be lifted by a hydraulic press is 80 "kg" .If the radius of the larger piston is five times that of the smaller piston, what is the minimum force that must be applied?

An effort applied on the small piston of a hydraulic jack lifts the load through a distance of 50 cm and the effort is displaced through 2 m. If the diameter of the larger piston is 28 cm, calcualte the area of the cross section of the smaller piston.

The area of smaller piston of a hydraulic pressure is 2cm square and that of larger piston is 20 cm square. How much weight can be raised on the larger piston when a force 200kg f is exerted on the smaller piston? g=10m//s^(2)

Two pistons of a hydraulic machine have diameters of 30.0 cm and 2.5 cm. What is the force exerted on the larger pistion when 40 kg wt. is placed on the smaller piston? If the smaller pistion moves in through 6 cm, how much does the other pistion move out ?

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?
