The hydraulic lift works on the principle of:

The hydraulic lift works on the principle of: Correct Answer Pascal's law

CONCEPT:

Pascal's Law:

  • According to Pascal's law for the transmission of fluids, whenever external pressure is applied on any part of a fluid contained in a vessel, it is transmitted undiminished and equally in all directions.

Hydraulic machines:

  • A number of devices, such as hydraulic lift and hydraulic brakes, are based on Pascal’s law.
  • In these devices, fluids are used for transmitting pressure.

EXPLANATION:

  • From the above, it is clear that hydraulic lift and hydraulic brakes are based on Pascal’s law. Hence, option 1 is correct.
