### Pascal's Principle - High School Physics and AP Physics Online

Answer: To solve this problem, first determine the force applied to the larger piston. If the maximum force on the chair is 1500N, you can now determine the maximum mass which can be lifted by recognizing that the force that must be overcome to lift the customer is the force of gravity, therefore the applied force on the customer must equal the force of gravity on the customer.

### How do Hydraulic Lifts Work? | Gartec Lifts

Hydraulic lifts work on a basic principle: to go up, a pump pushes oil into the cylinder, pushing the piston (which pushes the lift car) up. To go down, the valve opens and oil is allowed to flow back into the reservoir, and is pushed back using the gravitational force of the lift car. The diagram above shows this system. When the valve is closed, the oil can only go from the reservoir into ...

### Physics Complete: Hydraulic Lift

Hydraulic lift and hydraulic brakes are based on the Pascal's law. In these devices fluids are used for transmitting pressure. In a hydraulic lift as shown in figure below two pistons are separated by the space filled with a liquid. A piston of small cross section A1 is used to exert a force F1 directly on the liquid.

### Pascals principle and hydraulic lift | Physics Forums

Feb 10, 2012· I assume you are referring to the hydraulic lift in post#12. So the situation is that the piston with mass m and area A exerts a downward force on the fluid =mg. In exerting this downward force the piston creates a pressure =mg/A in the fluid. By Newton's third law the fluid therefore exerts an equal upward force on the piston.

### Pascal's Principle | Physics

Figure 1. A typical hydraulic system with two fluid-filled cylinders, capped with pistons and connected by a tube called a hydraulic line. A downward force F 1 on the left piston creates a pressure that is transmitted undiminished to all parts of the enclosed fluid. This results in an upward force F 2 on the right piston that is larger than F 1 because the right piston has a larger area.

### Why does the pressure of fluid increase when the diameter ...

The above equation is purely a kinematic condition that is taken from the statement of mass conservation for constant density, steady state flows. Next, if we take the further assumption that the fluid is inviscid and adiabatic (isentropic), then we know that the total pressure must be conserved.
