The AAR wheel arrangement system is a method of classifying locomotive (or unit) wheel arrangements that was developed by the Association of American Railroads.Essentially a simplification of the European UIC classification, it is widely used in North America to describe diesel and electric locomotives (including third-rail electric locomotives).
1. Center line, the central axis of a feature. 2. Class, for example, "paint per spec XYZ revision C type 1 class 2" may be abbreviated as "paint per spec XYZ REV C TY 1 CL 2" or even in some cases "paint per spec XYZ-C-1-2". (The latter practice is not uncommon but is cryptic for workers with minimal training and experience. The first two ...
The company settled on a gyroplane design for a number of reasons. "The gyroplane principle not only provides us with a safe and easy-to-operate flying car but it also enables us to make it compact and within existing regulations, which is the most important factor to build a useable flying car," said Mike Stekelenburg, Chief Engineer at PAL-V. [1] Pilots will require a Private pilot licence ...
where is the density of the fluid, is the average velocity in the pipe, is the friction factor from the Moody chart, is the length of the pipe and is the pipe diameter. The chart plots Darcy–Weisbach friction factor against Reynolds number Re for a variety of relative roughnesses, the ratio of the mean height of roughness of the pipe to the ...
The Great Northern Z-1 was a class of ten electric locomotives built for the Great Northern Railway [2] They were used to work the route through the second Cascade Tunnel. They were built between 1926–1928 by Baldwin Locomotive Works , with Westinghouse electrics, and stayed in service until dieselisation in 1956.
The GN numbered the units 5010–5017 and classified them Y-1 being painted in the "Pullman Green" (Dark green with the GNs logo plastered on the sides of the locomotive) paint scheme. After being involved in a wreck at Tonga, Washington in July 1945, the 5011 was rebuilt with a streamlined appearance using cabs from an EMD FT [ 1 ] ; the GN ...
Example of a Sankey diagram Sankey's original 1898 diagram showing energy efficiency of a steam engine. Sankey diagrams are a data visualisation technique or flow diagram that emphasizes flow/movement/change from one state to another or one time to another, [1] in which the width of the arrows is proportional to the flow rate of the depicted extensive property.
