4. Draw the influence lines for forces in bars AL and KJ. Using the influence lines, determine the maximum live load force (consider both tension and compression) produced by the 54k truck as it traverses the bridge, which consists of two trusses. Assume the truck moves along the center of the roadway so that one-half of the truck load is carried by each truss. Assume the truck can travel in either direction. 20 kips 24 kips 10 kips 2010- K 6@20 = 120 20 4. Draw the influence lines for forces in bars AL and KJ.
