Calculate the forces in members AC, AD, and DE for the loaded truss. Restraining link BC is horizontal. Forces are positive if in tension, negative if in compression. 9' 9' 660 lb D ä

HW 2 A 1. A truss is loaded with 600 lb as shown. Find the internal forces in all members. Be sure to state whether the members are in tension or compression. 6fy 6ft 6ft 6ft B 6ft 600 lb 6ft 6ft 6ft 6ft 6ft 6ft

Topic: Trusses For full credit you must use the method requested and show each FBD used to solve the problem. Problem 1: A Warren bridge truss is loaded as shown. a) Determine the force in members CE, DE, and DF using the method of sections and indicate if each member is in tension, T, or compression, C. Include a clearly labeled free-body diagram of your section. 6.25 ft 12.5 ft , 12.5 ft , 12.5 ft , 12.5 ft Ans. B D F H FCE = 8,000 lb, T 15 ft FDE = 2,600 lb, T FDF = 9,000 lb, C C E G I 12.5 ft12.5 ft 12.5 ft ' 12.5 ft ' 12.5 ft 6000 lb 6000 lb b) Using method of joints and the forces from part a) find the forces in members BD and DC and indicate if each member is in tension or compression.

For the fig. shown, compute the force on each member Of the truss. Indicate whether the member is in tension(T) Or compression 0. Answers must be tabulated like below. 48 kN 4m--4 m--4 DI Tor C 36KN(sample T(sample only) Member Force AB 4.5 m AC BC BD ВЕ Etc Until all members are included
