Question

Pascal's law or the Principle of transmission of fluid-pressure states that "pressure exerted anywhere in a confined incompressible fluid is transmitted equally in all directions throughout the fluid such that the pressure ratio (initial difference) remains the same."

1. A small piston with area A1 = 35 cm acts in a cylinder to lift a larger piston A2 = 600 cm Find the force on the small piston (F1) if the pressure in the system is 6600 pascals.

2. Find the weight the large piston could lift (F2) at a pressure of 6600 pascals.

3. If a force of F1 160 newtons acted on the smaller piston, what is the force F2 that the larger piston could support?

Explanation / Answer

Part A)

The formula for this is P = F/A

I am assuming you mean the area is 35 cm2 and not just 35 cm

6600 = F/.0035

F = 23.1 N

Part B)

For the large piston, I will assume you meant the area is 600 cm2 and not just 600 cm

6600 = F/.06

F = 396 N

Part C)

F/A = F/A

160/.0035 = F/.06

F = 2743 N
