Hydraulic+system

[|Hydraulics] - in applied science and engineering dealing with the mechanical properties of liquids. At a very basic level hydraulics is the liquid version of pneumatics.

Fluid mechanics provides the theoretical foundation for hydraulics, which focuses on the engineering uses of fluid properties.

In fluid power, hydraulics is used for the generation, control, and transmission of power by the use of pressurized liquids.

Hydraulic concepts such as pipe flow, dam design, fluidics and fluid control circuitry, pumps, turbines, hydropower, computational fluid dynamics, flow measurement, river channel behavior and erosion.

[|Hydraulic engineering] - civil engineering, concerned with the flow and conveyance of fluids, principally water and sewage. One feature of these systems is the extensive use of gravity as the motive force to cause the movement of the fluids. This area of civil engineering is intimately related to the design of bridges, dams, channels, canals, and levees, and to both sanitary and environmental engineering.

A [|hydraulic lift] for automobiles is an example of a force multiplied by hydraulic press, based on Pascal's principle. The fluid in the small cylinder must be moved much further than the distance the car is lifted.

[|Pascal's Principle] - Pressure is transmitted undiminished in an enclosed static fluid.

[|Hydraulic JudoBots] - Hydraulic engineering activity - constructing a robot that uses a simple hydraulic system to power a lifting arm and a pivot. Two robots face off and try to throw each other off of a table
 * What's the problem?**

Four components built separate from one another: the base, the stand, the arm, and the hydraulic system. The hydraulic system uses plastic syringes as pistons and water as the hydraulic fluid.

 * That's engineering**
 * [|check valve] - device that opens to permit the passage of fluid or air in one direction and closes to prevent passage in the opposite direction.
 * [|pump] - 1. A device for moving liquid or gas by decreasing or increasing the pressure on it. A device that increases the pressure on a fluid or raises it to a higher level. 2. As a verb, it means to move something energetically up and down.
 * Viscosity - the viscosity of the hydraulic fluid is an important factor in designing the capacity of the lift system.
