Temperature Coefficient of the Modulus of Rigidity of Aircraft Instrument Diaphragm and Spring Materials (1931)
NASA Technical Reports Server (NTRS) · leaf 11
can not be separated, modulus of rigidity for one tensile stress are given in since the internal strains produced in drawing the wire generally cause longitudinal curvature. Within the limits of experimental error it was found that for a given tensile stress, ~p,^is directly proportional to… … Tensile stress, Ib./sq. in. Figure 4.-EJrect of tensile stress and temiwatiire on the rigidity modulus of nickel silver. The moment of inertia / is in pounds-inches squared and the period P in seconds the absolute value of the slope of the curve through the experimental points appears to increase…
