The fiberstress caused by the moments from the two W^ forces will causea maximum tension at o which becomes less as it approaches a.This tensional fiber stress at o will be partially neutralized by… … Fig. 117. to the bed top over section 2 bh, Sm = tensional fiber stress at odue to the moments and St = resulting fiber stress at o. Taking W^ in two moments about ao and W^ in direct pressure Sm Z we have Wi = Sp A and M450 from which we obtain Sp = due to direct pressure and S„i = 2552X2X6 15312…
