A 1924 technical report from the NASA Technical Reports Server, with no stated title or named author, supplied for an unspecified audience of engineers. Its two photographs show experimental apparatus: a large framed test rig with a dynamometer hub and wiring at left, and a labelled instrument stand with lettered callout lines at right. A designer might take the stark, grey, documentary look of mid-century engineering photography, with its lettered callouts and exposed frames, as a source of industrial texture.
