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?

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 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?

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?

In a hydraulic lift the radius of small piston is 5.0 cm and that of larger piston is 15cm . Calculate the force F, if the mass of the car to be lifted is 1350 kg ( g=9.8 ms^-2 )

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.

Two piston of a hydraulic lift have diameters of 60 cm and 5 cm. What is the force exerted by the larger piston when 50 N is placed on the smaller piston ?
