In a hydraulic press, the small piston has an area of 2 square cm and the large piston has 20 square cm. A force of 50 N acts on the small piston. What force acts on the large piston?
Answer and explanation
Correct answer: D. 500 N
- Step 1: Pressure is equal everywhere in the fluid. Step 2. The force scales with area: 50 x 20 / 2 = 500 N. Answer: 500 N. Why not the others: these ignore the area ratio.
