Explanation Method adopted: Method of section. Assumptions: Consider the state of member as tension, where the force is pulling the member, and as compression, where the force is pushing the member. Consider the force indicating the right side as positive and the left side as negative, in the horizontal components of forces. Consider the force indicating upward as positive and downward as negative, in the vertical components of forces. Consider the clockwise moment as negative and the anti-clockwise moment as positive, wherever applicable. Apply the equation of equilibrium, wherever applicable. Entire truss: Show the free body diagram of entire truss as in Figure 1. Using Figure 1, Reactions: Moment about point A : Determine the vertical reaction at point E by taking the moment about point A . ∑ M A = 0 E y ( 40 ) − 1 , 000 ( 30 ) − 1 , 000 ( 20 ) − 1 , 000 ( 10 ) = 0 (I) Along the vertical direction: Determine the vertical reaction at point A by resolving the vertical component of forces. ∑ F y = 0 A y − 1 , 000 − 1 , 000 − 1 , 000 − 1 , 000 + E y = 0 (II) Along the horizontal direction: Determine the horizontal reaction at point E by resolving the horizontal component of forces. ∑ F x = 0 E x = 0 Conclusion: Solve Equation (I). 40 E y − 30 , 000 − 20 , 000 − 10 , 000 = 0 40 E y = 60 , 000 E y = 1 , 500 lb Substitute 1,500 lb for E y in Equation (II)
