| Why should you not use water in a hydrolic system |
|
Definition
| Water is not a good lubricant and it can cause the machine to rust, freeze, evaporate. |

1. You exert a force of 500 N on the small piston in a hydraulic lift. The small piston has an area of 100 cm2
2. The area of the large piston is 2500cm2, how many newtons of force will the large piston exert? |
|
Definition
5 pascals FORCE / AREA = PRESSURE
2500 / 100 = 25
25 x 500 = 12500 LARGE AREA / SMALL AREA 25x LARGER MULTIPLY BY FORCE |
