Locomotive operation; a technical and practical analysis (1904)
Henderson, G. R. (George R.), b. 1861 · Chicago, Railway Age · leaf 23
we let h — height of center of gravity of en^ 12 LOCOMOTIVE OPERATION. gine above the rail; and a ^= the gauge of track, we find that a — is the tangent of the angle where the resultant force will2h just strike the rail, therefore, to insure stability, the value C a — must be less than —. However,… … In Fig. 4, let a and h represent the gauge of track andheight of center of gravity, as before, and e the elevation ofthe outer rail. The other letters represent certain dimensionsin order to make the necessary calculations. Then from similartriangles, we have ah d d he — = — and j= \- i = 1 ; p i ^…
