1. Force and Pressure Pascal’s Principle

2. Pascal’s Principle Pressure applied to an enclosed liquid is transmitted equally to every part of the liquid

3. 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.

4. 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
