1- A device used to absorb mechanical shocks,as a hydraulic or pneumatic piston used to dampon the shaking substained in moving vehicle.
2-when you push the brake down it pushes the liquid in the car down to the brake pads and the preassure pushes the padds onto the wheels to stop the vehicle from moving.
3- hydraulic brakes are used in vehicles to produce a breaking force on all the wheels simultaneously at the instant the brake pedal is applied
4- the brake pedal is directly attached to the master cylinder and acts as a lever to apply preassure aqainst the master cylinder.
5- the hydraulic elevators are baed on the motor mechanism for hydraulic elevator.the system operates on the elevator valves, submersible motors and screw pumps.
6- this pressure is transmited through the oil to the large cylinder. thus a force f2 which is strong enough to lift a heavy load.
7- by forcing water through compressed tube shooting water on the plates at a rapid speed.
8- the preassure produced by the force applied through the oil to the large piston. thus the large piston is pushed up by the large force
9- improves substantially the performance of the elevation control system. it uses a hydraulic accumalator and preassure switch arrangement to determine when the electric-motor-driven pumps run
10- power steering reduces the steering effort on vehicles by using an external power source to assist in turning the tire. in this case, the external power source is the fluid power generated by the engine.
11- an example of a simple hydraulic system is a hydraulic lift which is used to lift vehicles. the system has a mechanical advantage of both power input and distance output
12- modern variations may employ compressed air, rubber, springs,peristaltic pumps, or hydraulic preassure to propel the water.
13-hydraulic pistons have changed many aspects of our lives. also called hydraulic cylinders and hydraulic rams, pistons are found in automobiles, aircrafts, amusment park ride, farm equipment and throughout construction, and factories.
14- hydraulic brakes are used in vehicles to produce a breaking force on all the wheels simultaneously at the instant the brake pedal is applied.
