Multiplying the force

Using a 10 ml and a 2.5 ml syringe lift a 10kg brick with as little effort as possible.

Which set up would you use?

2.5ml syringe is used to push the 10ml syringe.

The 10ml syringe is used to push the 2.5ml syringe. This system can hardly budge the brick.

The hydraulic system above can lift the brick with little effort. The effort is magnified by this system

The system on the left can hardly budge the brick.

Even though the brick may be lifted higher, this hydraulic system cannot generate the force required.

Hydraulic Pressure

Pressure produced by the effort piston passes through the fluid (water) to the load's piston.

This piston has a larger area and so the pressure from the smaller piston presses on a larger area.

This produces a larger force, in this case 5 times the force.
