2 kN D 2 kN F 2 kN В 30° 60° G A E 5 m 5 m 5 m A symmetrical truss of a house roof is loaded as shown in Figure above. All loads are perpendicular to the inclined members. Member BC with DE, and CD with EF are parallel with each other. The truss is supported by a pin at A and a roller at G. (a) From your observation (without calculation), determine the zero-force member. Explain why it is a zero-force member? (b) Determine the forces in members DF, DE and CE. Identify the state of these members. Summarize the forces in table as below. Member Force State DF DE CE
