Pascal's Law states that the pressure exerted anywhere in a confined liquid is transmitted equally and undiminished in all directions throughout the liquid.
Hydraulic Jack :
A hydraulic jack is used for lifting heavy vehicles such as are , trucks, etc. In service stations for their repairing.It works on the Pascal's principle .
Working :
We have an enclosed volume of fluid in a U SHAPED TUBE.
The fluid is enclosed in the tube by two leak proof pistons in each arm.
The ratio of cross section areas of the right and tube tubes is A2 : A1 and A2> A1
When a force F1 is applied to the left piston the excess pressure acting on the fluid volume is F1/A1.
According to Pascal's principle , this excess pressure is transmitted equally throughout the fluid volume.
every unit area of the fluid experience pressure of F1/A1.
The excess pressure in the right side tube is F1/A1. the upward force acting on the right piston is F2= A2x F1/A1 which is larger in magnitude than F1.
Thus the application Of Pascal's results in large upward force on the right piston when a small downward force is applied on the left piston.

Hello Dear.
Here is your answer---
Hydraulic Lift is also known as the Hydraulic Jack. It works on the Principle Pascal's Law.
Hydraulic Jack is used for lifting heavy vehicles such as Cars, Trucks, etc.
Construction,
Hydraulic Jack consist of two cylindrical Vessels which are connected to each other with a tube having a valve.The one cylindrical vessels is narrower than the other. The Piston of the narrower cylindrical vessels is attached to the Lever ad the piston of the Wider cylindrical vessels has a platform for lifting the Vehicles.The Vessels are filled with a liquid mostly Water is used).
Working---
When Handle of the Lever is Pressed Down by applying an Effort, the valve in the tube opens because of the increase in pressure in the Narrower Cylinder. The liquid runs out from the narrower to the wider cylinder. As a result the Piston in the Wider cylindrical Vessels rises the Objects placed in the Platform.
When the Objects reaches the Desired Height, the Handle of the Lever is no longer Pressed. The valve get closed (since the pressure on either side of the Valves become same) so that the liquid does not run back from the Wider Cylindrical Vessels to the Narrower cylindrical Vessels.
Pascal's Law states that the pressure exerted anywhere in the liquid in transmitted equally and Undiminished in all Directions throughout the Liquid.
From the Proved working of the hydraulic Jack or Hydraulic lift and the Pascal's law, We can observe that it works on the same Principle of Pascal's law.
Hope it helps.
Have a Marvelous Day.
