Hydraulic systems use fluids to transmit power. They are commonly found in various applications, from everyday objects to heavy machinery. Here are two examples:
1. Car Brakes
Car brakes are a classic example of a hydraulic system. When you press the brake pedal, you're pushing a piston in a master cylinder filled with brake fluid. This pressure is then transmitted through hydraulic lines to the brake calipers at each wheel. The calipers then push brake pads against the rotors, slowing the car down.
- How it works: The brake pedal is connected to a master cylinder. The master cylinder is filled with brake fluid. When you press the brake pedal, the master cylinder piston pushes the brake fluid through the hydraulic lines to the brake calipers. The brake calipers then use the hydraulic pressure to push the brake pads against the rotors, slowing the car down.
2. Excavator Arm
Excavator arms use hydraulic cylinders to lift and move heavy objects. The operator controls the flow of hydraulic fluid to the cylinders, which then extend or retract, allowing the arm to move.
- How it works: Hydraulic fluid is pumped into the cylinders, causing them to extend and lift the excavator arm. The operator can control the flow of hydraulic fluid to the cylinders, allowing them to control the arm's movement.
