# Pascal's Principle - Example 1

Example 1:
In a hydraulic system the large piston has a cross-sectional area A2 = 200 cm² and the small piston has cross-sectional area A1 = 5 cm². If a force of 250 N is applied to the small piston, what is
a. the pressure exerted on the small piston
b. the force F, produced on the large piston?

a. Pressure exerted on the small piston
$P= F A = 250 5 =50N/c m 2$
b. Pressure exerted on the large piston = Pressure exerted on the small piston
$P= F A (50)= F (200) F=10,000N$
