Homework Answers
Forces in member BF and HD are zero as both the members meet perpendicular at node F and H. Thus by equilibrium of node F and H gives sum of forces in y direction is zero, thus forces in BF and HD is zero.
Also GD is zero as HD is zero and and sum of forces in direction of member DC and DE is zero, that shows force in member GD should be zero.
