atest deflection a maximum deflection ? In problems involving two intervals, such as Ex. 91,it is advisable to use a different origin for each interval.This artifice is solely used to simplify the mathematicalcalculations. Great care must be taken to keep thischange of origin constantly in mind… … Fig. 43 origin at A, x increasing positively toward B; for theright interval let C be the origin and assume x to in-crease positively towards B. Then for the left intervalwe have d2y W(l - a) dx2 I x, EIdy_W(l-dx 2 I Wc1; (1)(2) DEFLECTION OF BEAMS 81 and EIy = W(J6~a)^ + C1x + C2. . . (3) For the…
