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 ...
Hydraulic tappet. A hydraulic tappet, also known as a hydraulic valve lifter or hydraulic lash adjuster, is a device for maintaining zero valve clearance in an internal combustion engine. Conventional solid valve lifters require regular adjusting to maintain a small clearance between the valve and its rocker or cam follower.
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 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 ...
Slack tide. Slack tide or slack water is the short period in a body of tidal water when the water is completely unstressed, and there is no movement either way in the tidal stream. It occurs before the direction of the tidal stream reverses. [ 1] Slack water can be estimated using a tidal atlas or the tidal diamond information on a nautical ...

The reciprocating motion of a non-offset piston connected to a rotating crank through a connecting rod (as would be found in internal combustion engines) can be expressed by equations of motion. This article shows how these equations of motion can be derived using calculus as functions of angle ( angle domain) and of time ( time domain) .
Scharfenberg coupler on a Southeastern Class 395. Video of ICE T coupling at Leipzig Hauptbahnhof. A coupling or coupler is a mechanism, typically located at each end of a rail vehicle, that connects them together to form a train. The equipment that connects the couplers to the vehicles is the draft gear or draw gear, which must absorb the ...
