The diagram shows a hydraulic machine using a liquid to transmit a force. When piston A is pressed, the force is transmitted and piston B moves.
The area of piston A is 5.0 cm2 and the area of piston B is 25 cm2.
Piston A is pressed with a force of 15 N. What is the force produced at piston B?
Use the equation:
pressure=forcearea \text{pressure} = \frac{\text{force}}{\text{area}} pressure=areaforce3.0 N3.0\text{ N}3.0 N
