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?

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

the focus of lesson 1 is newton's first law of motion - sometimes referred to as the law of inertia. newton's first law of motion is often stated as. an object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.
