Determination of the Maximum Control Forces and Attainable Quickness in the Operation of Airplane Controls
This is a 1930 NACA technical memorandum, No. 583, issued by the National Advisory Committee for Aeronautics and preserved in the NASA Technical Reports Server, written for aeronautical engineers to report measured control forces on airplanes. The single photograph shows a cluttered wooden test rig with a pulley, cable and lever assembly, captioned Fig. 1 Test outfit. For designers it offers a raw view of early experimental engineering: dense timber framing, exposed rigging and gauges, useful for industrial or mechanical texture.
