How a hydraulic press works?

What is the expression for mechanical advantage of a hydraulic press ?

The mechanical advantage of a hydraulic press is 5. A car of mass 1500 kg is lifted by when placed on a piston of a hydraulic press of area of cross section 5 m^(2) . Find the area of cross section of pistion of piston where the effort is applied.

Shows a hydraulic press with the larger piston of diameter 35cm at a height of 1.5 m relative to the smaller piston of diameter 10cm. The mass on the smaller piston is 20gk. What is the force exerted on the load by the lerger piston ? The density of oil in the press is 750 "kgm"^(-3).

Ac cording to Pascal's law, the increases in pressure at one point f enclosed liquid in equilibrium of rest is transmitted equally to all other points of the liquid and also to the walls of the container, provided the effect of gravity is neglected. Hydraulic lift and hydraulic brakes are based on this very law. Read the above passage and anser the following question : (i) How do hydraulic brakes work ? (ii) What are the implication of this law in day to day life ?

Give the uses of a hydraulic press.

The area of the smaller piston of a hydraulic press is 1cm^2 and that of larger piston of a hydralic press is 1cm^2 .How much weight can be raised on the larger piston by a 200 kg f exerted on the smaller piston?

The area of the smaller piston of a hydraulic press is 1 cm^(2) and that of larger piston is 22 cm^(2) . How much weight can be raised on the larger piston by a 200 kg f exerted on the smaller piston?
