Measuring vibration and torque with the oscillograph
A 1924 technical report titled Measuring vibration and torque with the oscillograph, catalogued through the NASA Technical Reports Server and drawn from NASA technical report records for engineers and researchers. The picture is a cropped plate of oscillograph traces, with one panel of dense, irregular wavy lines and a second panel of smooth, regular sine curves, captioned as figures 10 and 11 showing shaking chute motion and vertical distance of chute. A designer could draw on its stark wave-line patterns for rhythmic linework, oscilloscope-style graphics, or diagrammatic texture.
