The voltage magnitude is also assumed to be 1 p.u. at the slack bus. The slack bus provides or absorbs active and reactive power to and from the transmission line to provide for losses, since these variables are unknown until the final solution is established. The slack bus is the only bus for which the system reference phase angle is defined ...
In railroading, slack action is the amount of free movement of one car before it transmits its motion to an adjoining coupled car. This free movement results from the fact that in railroad practice cars are loosely coupled, and the coupling is often combined with a shock-absorbing device, a "draft gear", which, under stress, substantially increases the free movement as the train is started or ...
The slack angle is the V-shaped angle created when a performer stands in the middle of the walking part of the wire. The angle depends on how long or short the wire is relative to the distance between two anchor points. This also affects the amplitude of the wire's swing side to side. Some slackwire artists change the angle of the wire during ...
A railway air brake is a railway brake power braking system with compressed air as the operating medium. [ 1] Modern trains rely upon a fail-safe air brake system that is based upon a design patented by George Westinghouse on April 13, 1869. [ 2] The Westinghouse Air Brake Company was subsequently organized to manufacture and sell Westinghouse ...

The fleet angle is defined as the largest angle of the rope between the first sheave and the drum flange, relative to the centre line of the drum. With all type of drums, the rope is subject to a fleet angle which impacts on its behaviour and affects lifespan. Fleet angle should be between 0.25° and 1.25°, depending on the rope construction.
Peek-a-boo's key principles are built upon the "Bad intentions" concept [citation needed], which emphasize the D'Amato philosophy.The general idea is that the Peek-a-boo practitioners are counterpunchers, who contrary to accustomed ways of counterpunching perceived as constantly backing-up and jabbing from the safe distance, move forward and do it with a lot of aggressiveness by constantly ...
