Q .

The Hydraulic press used to lift a car is based on the following principle

Pascal's Principle

Magnus Effect

Bernoulli's Principle

Archimedes Principle

Correct Answer : Pascal's Principle

However, because Aâ‚ has 10 times the area of Aâ‚, it will produce a force (Fâ‚‚) that is 10 times greater than the original force (Fâ‚). Through Pascal's principle, a relatively small force exerted on a hydraulic press can be magnified to the point where it will lift a car.
