Question

A hydraulic lift is used to lift a heavy box that is pushing down on a 1.5-m2 piston with a force of 1,700 N. What force needs to be exerted on a 0.12-m2 piston to lift the box?

Answer 1

Answer:

136 N

Explanation:

Pressure on large piston = pressure on small piston

F₁ / A₁ = F₂ / A₂

1700 N / 1.5 m² = F / 0.12 m²

F = 136 N
