Force and Pressure
Pascal’s Principle
Pascal’s Principle
Pressure applied to an enclosed liquid is transmitted equally to every part of the liquid
Question
F1 = 15 N
F2 = ? N
A1 = 24 m2
A1 = 4 m2
The figure shows a hydraulic system. Base on the information, determine the value of F2.
Solution
From Pascal’s principle
P1 = P2expand the formula
F1/A1 = F2/A2 rearrange the formula
F2 = (A2/A1) × F1 substitute the value
F2 = (24/4) × 15
F2 = 90 N
