1. A small bridge is carrying a truck moving from left to right. Using influence lines for beams: a. Compute the max. ordinate of the influence line to obtain max positive moment at point B. b. Compute the position of P1 from point A to produce maximum positive moment at B. c. Compute the maximum positive moment at B due to the series of concentrated loads. P1 P2 P3 B COM D 4m 4m 2m Truck wheel loads: P1 P2 P3 P1 = 128 P2 = 103 P3 = 53 2m 3m
