  1. It turns out that the FEA for a bicycle wheel was done before 1903:

    [After an impressive page of equations for an 8-spoke bicycle wheel]

    "As a particular instance let W [weight] = 1000 pounds . . . Then the
    stress for all the spokes except [lowermost spoke] is 76 pounds
    tension, and that in [lowermost spoke] is 924 pounds compression; also
    the stress in each segment of the rim is about 98 pounds compression.
    It thus appears that the vertical spoke under the hub carries nearly
    all the load as a compressive stress, and that as the wheel slightly
    turns this is turned into a small tensile stress."

    --"A Text Book on Roofs and Bridges," 5th ed., 1903, Merriman & Jacoby
    p. 149-150
