Calculate the strainin BD and AB as in Fig. 120.Multiply half the strain in BD(or AB) by the secant of halfthe angle the two masts (orguys) make with… … Fig. 122. sustain a single load P.v i5; on Ci = 1/2 PX CA STRESSES IN FRAMED STRUCTURES. 517 are of equal length, in which case 1/2 of P is supported by each abutmentC and D. If they are unequal in length (Fig. 124), then, by the principleof the lever, find the reactions of the abutments Pi and R2.…
