Summary
| Description |
English: It is a plot of Curve resistance of railroad freight cars tested in the Soviet Union in the 1960's. It shows how the curve resistance depends on velocity in a banked curve. Plotted with Gnuplot based on averaging data (measured with a ruler) from Fig. 5.2, p.115 of the Russian book: Астахов, П.Н. "Сопротивление Движению железнодорожного подвижного состава" (Resistance to motion of railway rolling stock), Транспорт, Москва, 1966. (Vol. 311 of ISSN: 0372-3305). |
