Determine the forces in members BC, BE, and BF. The triangles are isosceles. The forces are positive if in tension, negative if in compression. 220 A B C 62 670 /67 670 620 D G F E L Answers: BC = i BE = BF = iDetermine the forces in members BE and CE of the loaded truss. The forces are positive if in tension, negative if in compression. 3.9 KN 4.0 KN 3.1 m 44 D 3.4 m 3.4 m BC = CD Answers: BE = KN CE = i KN
