The hydraulic press shown in the figure is used to raise the mass M through a height of 0.5 cm by performing 500J of work at the small piston. The diameter of the large piston is 10cm , while that of the smaller one is 2 cm . The mass M is

Two pistons of a hydraulic machine have diameters 20 cm and 2 cm. Find the force exerted on the larger piston when 50 kg wt is placed on the smaller piston. When the smaller piston moves is throught 50 cm, by what distance the other piston moves out ?

The pressure exerted on the smaller and the larger piston of a hydraulic machine is 15 Pa Calculate the force exerted by it on the larger piston, if the area of cross section of the larger piston is 4 m^2 .

Figure shown a hydraulic press with the larger piston if diameter 35 cm at a height of 1.5 cm at a height of 1.5 m relative to the smaller piston of diameter 10cm. The mass on the smaller piston is 20 kg. What is the force exerted on the load by the larger piston? The density of oil in the press is 750 kh//m^(3) . (Take g=9.8 m//s^(2)) .

In a hydraulic lift, used at a service station the radius of the large and small piston are in the ration of 20 : 1 . What weight placed on the small piston will be sufficient to lift a car of mass 1500 kg ?

In a hydraulic press, radii of connecting pipes, r_(1) and r_(2) are in the ratio 1:2 . In order to lift a heavy mass M on the larger piston, the small piston must be pressed through a minimum force f equal to

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?

A force of 50 kgf is applied to the smaller piston of a hydraulic machine. Neglecting friction, find the force exerted on the large piston, if the diameters of the pistons are 5 cm and 25 cm respectively.

A disc of mass M kg and radius R metre is rotating at an angular speed of omega rad/s when the motor is switched off. Neglecting the friction at the axie, the force that must be applied tangentially to the wheel to bring it to rest time t is
