The primary principle behind the functioning of a hydraulic system is Pascal's Law. Here's a step-by-step explanation:

1. Pascal's Law states that when there is an increase in pressure at any point in a confined fluid, there is an equal increase at every other point in the container.

2. A hydraulic system works on this principle. It consists of two pistons and an oil-filled pipe connecting them.

3. When force is applied to one piston, it creates pressure in the oil.

4. This pressure is then transmitted to the second piston through the oil in the pipe. This causes the second piston to move.

5. The force that the second piston can exert is the pressure in the oil times the area of the second piston. This is why a small force applied to a small area can lead to a larger force over a larger area.

6. In this way, a hydraulic system can increase force, making it useful for systems such as brakes and hydraulic presses.
