Using the method of sections, determine the forces inmembers BG, CI, and CD. Express your answers in terms of P (e.g.FA= 0.5P)3.1 Use the concepts of moment and force equilibrium, find the reactions atpoint A (FAx and FAy) and point E (FEy).3.2 Find FBG first. Cut through BC, BG, and GF, consider the Left-Hand Side(LHS) section as a whole, find FBG by considering the Free-Body Diagram(FBD), and equilibrium of forces in the y-direction.3.3 Now find FCI and FCD. Cut through CD, CI, and HI, consider the RHSsection as a whole, find FCI by considering the FBD, and equilibrium offorces in the y-direction. Then, find FCD by taking moment at point I, andconsider the concept of moment equilibrium.
