A hydraulic press has a small piston of radius 0.05 m and a large piston of radius 0.2 m. What force is required on the small piston to lift a 1000 N load?
Q1. A hydraulic press has a small piston of radius 0.05 m and a large piston of radius 0.2 m. What force is required on the small piston to lift a 1000 N load?
Answer: 62.5 N
Explanation: F₁/A₁ = F₂/A₂; F₁ = F₂ * (A₁/A₂) = 1000 N * (0.05/0.2)² = 62.5 N; correct application of Pascal's law.
