MENTS OF MECHANICS OF MATERIALS Knowing the stress in AF and the external force AB, an inspec-tion of joint ABGF shows BG and OF to be struts, and they areso marked in the frame. The section xy cuts the members BG,GF, and FE, two of these members intersecting at E. Consider-ing the part of the… … Sj cos 30 R2=5 tons Fig. 100. Calling Si the stress in GF, and taking moments about the leftsupport, we have 54 X 12.5 sin 30° = 2 X 6.25, whence 6*4 = 2 tons. These results are the same as were obtained from the reciprocaldiagram of Fig. 99. In the examples of the section method just given the…
