SUMMARY

The discussion focuses on solving for the forces in members of a structural system under a load of magnitude P = 106 N. The members ABEF and BCD are considered rigid bodies, and the problem requires calculating the reaction forces at points D and G to maintain equilibrium. Key dimensions provided are a_c = 3.60 m and b_c = 2.40 m. The solution involves applying static equilibrium equations and constructing a free body diagram to determine the magnitudes of the reactions.

Homework Statement



As shown, a load of magnitude P is applied to a structure. Assuming that all members are weightless and that ABEF and BCD are rigid bodies, find the magnitudes of the reactions at D and G needed to maintain the structure in equilibrium.

Assume the following values: a_c = 3.60 m, b_c = 2.40 m, and P = 106 N. Express your answers numerically in Newtons to three significant figures separated by a comma.

Fd, Fg = ?

Any help would be greatly appreciated.
