There are at least three kinds:
- hydraulic jack: A pump with a small-diameter piston and cylinder is operated to produce hydraulically pressurised liquid. This liquid is directed again a large piston. Since this piston is larger that the one in the pump, although the force acting on, say, a square centimetre is the same the overall force is much larger and great enough to lift a car.
- scissor jack: The jack is in the form of a four-sided figure with hinges at the corners. A screw is mounted horizontally so that it can rotate at one corner of the square and turn inside a thread at the opposite corner. As the screw tightens it pulls the opposite sides of the four-sided figure together forcing the top of the figure up.
- rack-and-pinion jack: The jack consists of a long, large diameter screw with a threaded hook on it. As the screw is turned the hook is pulled up.

How hydraulics are developed in car jacks?
A hydraulic jack works by pumping fluid from a reservoir into a small cylinder, which then pressurizes a larger cylinder. A full stroke of the smaller piston creates a small stroke of the larger piston, creating a mechanical advantage. The mechanical advantage allows the jack user to lift an object (i.e. a car) much heavier than they would otherwise be able to lift by themselves, just by lifting it a tiny bit at a time. The fluid pumped into the larger cylinder is prevented from escaping by a valve, which can then be opened allowing the fluid to return to the reservoir when the user is ready to lower the object, or vehicle.
