The steel truss shown in Figure 1.C is anchored at A and supported on rollers at B. If the truss is so designed that, under the given loading, all tension members are stressed to 100 N/mm and all compression members, to 80 N/mm, find vertical deflection of point C. Take E=2105 N/mm Also find the lateral displacement of end B. 3 A 45 KN 45 KN 4 m 4 m 4 m B D Figure 1. C C
