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 can be lifted by a hydraulic press is 100kg. If the radius of the larger piston is six times that of a smaller poston. What is the minimum force (in kg wt) that must be applieed? Use g=10ms^(-2) .

The diameter of smaller piston of a hydraulic press is 3 cm that of a larger piston is 20cm. If a weight of 50 kg f is placed on the smaller piston, what will be the force exerted by the larger piston? If the stroke of smaller piston is 5cm, calculate the distance through which the larger will move after 6 strokes?

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 diameter of the smaller piston of a Hydraulic press is d_1 and the larger piston is d_2 . If the applied force on the smaller piston is F_1 then the value of the force F_2 on the larger piston is

A hydraulic press can lift 100 kg when a mass 'm' is placed on the smaller piston. It can lift _____kg when the diameter of the larger piston is increased by 4 times and that of the smaller piston is decreased by 4 times keeping the same mass 'm' on the smaller piston.

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 mass of 1000 kg is to be raised with the help of a hydraulic press. The ratio of the diameters of its pistons is 1 : 5 and the mechanical advantage of the press is 4. What force has to be applied on the smaller piston of the press?

The ratio of the diameters of the smaller and the larger pistons of a hydraulic press is 1 : 5. The ratio of the lengths of the arms of the lever used is 1 : 8. If a force of 490 N is applied at the handle of the lever, then how much thrust will be developed on the larger pistion?

The lengths of the two arms of a first class lever used in a hydraulic press are 20 cm and 100 cm. The radii of the larger and the smaller pistons are 30 cm and 3 cm respectively. If a force of 196 N is applied at the handle of the lever, then what thrust will be developed on the larger piston?
