Stresses in wire ropes bent over sheaves
An engineering thesis by William Francis Coleman and Daniel Maltby Rugg, submitted at the University of Illinois in 1910, testing how wire ropes behave when bent over sheaves of different diameters. The plates are hand-drawn load-elongation graphs inked on green grid paper, each with paired rising curves, small circled data points, and captions naming rope and sheave sizes, useful as ready-made technical chart textures and handwritten axis lettering.
