A hydraulic press can lift 100 kg when a mass 'm' is placed on the smaller piston. It can lift _______ kg when the diameter of the larger piston is increased by 4 times and that of the smaller piston is decreased by 4 times keeping the same mass 'm' on the smaller piston.

Your answer

Answer and worked solution

Official answer: 25600

Pascal. Load ∝ $\frac{A_{large}}{A_{small}}$ , which grows by $16\times16=256$ : $100\times256=25600$ kg.

Answer: 25600
