answerIf you wish to check the reaction forces at A and H, pass
a cutting plane through members AB, AG, and AH. As shown in the
figure above, the cutting plane b-b cut these members. Take the
section above b-b and replace the cut members by internal force to
maintain equilibrium. Solve for the internal force in members AB,
AG, and AH. With these forces known, you can then check the
reactions through joints A and H. The free body diagram of the
section above b-b is similar to the free body diagram of section
above a-a. See the solution of section a-a below for easy reference
of doing the section b-b.From section above a-a
