Ahydraulic lift is used to lift a heavy box that is pushing down on a 3.0m2 piston with a force of 1500 n. what force needs to be exerted on a 0.08 m2 piston to lift the box?

40 N

Explanation:

= Force on piston = 1500 N

= Area of the first piston = 3 m²

= Area of the second piston = 0.08 m²

=  Force on the second piston

From Pascal's law we have

The force that is needed to lift the box is 40 N

54 degrees incident angle = reflected angle

angle is from normal turned to line of ray
