Tables of stiffness and carry-over factor for structural members under axial load
A 1938 NASA technical report of tables giving stiffness and carry-over factors for structural members under axial load, prepared for engineers and structural analysts. The single picture is a page of typeset formulas defining alpha and beta in terms of L/j with a hyperbolic cotangent term, plus j as the square root of EI over P, useful to a designer only as a reference for mathematical notation layout.
