Question

Which statements concerning Pascal's law and an ideal hydraulic machine are correct?

G1 Physics · Accepted Answer

Pascal's law states that an applied pressure change is transmitted through a confined fluid. Therefore A is correct. For two pistons, F₁/A₁ = F₂/A₂. A larger output-piston area gives a larger output force, so B is correct. Incompressibility requires A₁x₁ = A₂x₂. Hence the piston with smaller area moves through a larger distance, so C is correct. Hydraulic brakes use transmitted fluid pressure to produce braking force at wheel cylinders, so D is correct. Therefore all four statements are correct.
