Chapter 1 PRESSURE AND DENSITY
TRANSMISSION OF PRESSUREThe Hydraulic Machine
The hydraulic machine functions based on two liquid properties:
- Liquids are incompressible
- Pressure in a liquid is transmitted to all parts of the liquid.
Push down on the smaller piston with a force F1 and area A1, the pressure will be transmitted through the liquid will act on the larger piston and the larger piston will be forced up with a force F2. The effort needed to push down on a smaller piston is less than the load lifted.
Examples of hydraulic machines:
- Hydraulic Jack used to lift a car.
- Hydraulic Press used to shape mechanics.
- Hydraulic Brakes used to spot moving cars.
