Pascal's principle states that pressure applied to an enclosed liquid is transmitted equally throughout the liquid. The document then presents a hydraulic system problem where a force of 15N is applied over an area of 24m^2. Using Pascal's principle and rearranging the pressure formula, the force over the smaller area of 4m^2 is calculated to be 90N.

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

3. QuestionF1 = 15 NF2 = ? NA1 = 24 m2A1 = 4 m2The figure shows a hydraulic system. Base on the information, determine the value of F2.

4. SolutionFrom Pascal’s principleP1 = P2expand the formulaF1/A1 = F2/A2 rearrange the formulaF2 = (A2/A1) × F1 substitute the valueF2 = (24/4) × 15 F2 = 90 N
