A Simple Hydraulic System:
A closed toothpaste tube can be considered as an example for a simple hydraulic system. The toothpaste can be considered as a hydraulic fluid working inside the system which is confined. Four or five holes are made on the tube. By keeping the cap of the toothpaste tube closed, apply pressure at a particular point on the tube. This makes the toothpaste to come out from all the holes evenly. This is a simple example to understand Pascal’s law. Thus force applied at a particular point on a fluid in closed system, transfers equal force on all other parts of the system. Further, the force acts perpendicular to the walls of the confined area.
Other example is the hydraulic brakes used in automobiles. The driver applies force at the break pedal (one particular point on fluid in closed system), thus transmitting this force onto the hydraulic fluid under the piston (break pedal), transfers equal force to all other brake shoes, thus stopping the vehicle.
There are several other areas where hydraulics are applied. They are:
1. Automobile garage
2. Petrol pumps
3. Measuring weights of heavy-lift trucks
4. Hydraulic cranes
5. Automobile steering gears
6. Automobile brake, (disc brakes)
7. Ship's steering gear
9. Aircraft's rudder and other maneuvering systems
10. Industries and power plants
11. Servo machanisms and control systems etc.
Also, this same principle is used in hydraulic lifts and other machineries. In the next article we will discuss how hydraulic presses are used in industries.
