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 = 40 cm acts in a cylinder to lift a larger piston A2 = 550 cm Find the force on the small piston (F1) if the pressure in the system is 6400 pascals.
2. Find the weight the large piston could lift (F2) at a pressure of 6400 pascals.
3. If a force of F1 300 newtons acted on the smaller piston, what is the force F2 that the larger piston could support?
Explanation / Answer
1. P=F/A P1*A1=F1 2.56 kN= F1 2. F2/F1= A2/A1 F2= 35.2 kN 3. F2/F1= A2/A1 F2= 4.125 kN
