Hydraulic Fundamentals
Hydraulic Advantages. Hydraulics has many advantages not always found in electrical and mechanical type drives. Hydraulic cylinders and motors can be operated at variable speeds. By varying the volume flowing into the actuator (cylinder or motor) the speed is changed. The hydraulic cylinder or motor can be stalled under a load.

14.3 Pascal's Principle and Hydraulics
Significance This value is the force exerted by each of the four wheel cylinders. Note that we can add as many wheel cylinders as we wish. If each has a 2.50-cm diameter, each will exert 1.25 × 10 4 N. 1.25 × 10 4 N. A simple hydraulic system, as an example of a simple machine, can increase force but cannot do more work than is done on it.

Fundamentals of hydraulics system engineering
Cavitation is the formation of vapour bubbles inside the fluid due to the pressure decrease below the vapour pressure (phase change) Fluid cavitation. In fluid systems the term "cavitation " usually refers to the formation and collapse of cavities in the liquid. The cavities may contain air or gas. If the pressure is low enough, the liquid ...

Hydraulic Systems Basics
All hydraulic circuits are essentially the same regardless of the application. There are four basic components required; a reservoir to hold the fluid; a pump to force the fluid through the system; valves to control the flow; and an actuator to convert the fluid energy into mechanical force to do the work.
