Alpha Centauri (α Centauri, α Cen, or Alpha Cen) is a triple in the southern of . It consists of three stars: Rigil Kentaurus (α Centauri A), Toliman (α Centauri B), and (α. .
To the naked eye, α Centauri AB appears to be a single star, the . Their apparent angular separation varies over about 80 years between 2 and 22. .
Alpha Centauri is a triple star system, with its two main stars, A and B, together comprising a component. The AB designation, or older A×B, denotes the mass centre of a main binary system relative to c. .
The Alpha Centauri system as a whole has two confirmed planets, both of them around Proxima Centauri. While other planets have been claimed to exist around all of the stars, none of the discoveries have been confirmed..

[pdf] Electric power is the product of two quantities: and . These two quantities can vary with respect to time () or can be kept at constant levels (). Most refrigerators, air conditioners, pumps and industrial machinery use AC power, whereas most computers and digital equipment use DC power (digital devices plugged into the mains typically have an internal or external to convert from AC to DC power). AC power has the a.
[pdf] Fluid power systems can produce high power and high forces in small volumes, compared with electrically-driven systems. The forces that are exerted can be easily monitored within a system by gauges and meters. In comparison to systems that provide force through electricity or fuel, fluid power systems are known to have long service lives if maintained properly. The working fluid passing through a fluid motor inherently provides cooling of the motor, which must be separatel.
