The diameter of the large piston of a hydrolic press is 20 cm,and the cross-sectional area of the small piston is 5cm².if the force of 400N is applied to the small piston,what is the resulting force exerted on the large piston?

We can use the principle of Pascal's Law which states that pressure applied to a fluid is transmitted uniformly in all directions. Therefore, the pressure applied to the small piston will be transmitted to the large piston, resulting in a larger force.

First, we need to find the pressure applied to the small piston:

Pressure = Force/Area

Pressure = 400N/5cm²

Pressure = 80N/cm²

Now, we can use this pressure to find the resulting force on the large piston:

Force = Pressure x Area

Force = 80N/cm² x π(10cm)²

Force = 80N/cm² x 100πcm²

Force = 8000πN

Therefore, the resulting force exerted on the large piston is approximately 25,132 N (8000π ≈ 25,132).
