same as in equation (110). If the metal be perfectly elastic, Stodolas formulas give S = as the stress near the center when d approaches 0 — 9or more than twice the value given in (122). In view of the imperfect elasticity of the metals used the true value will prob-ably be between these two. This… … Then m Fig. 97.
