rs are both compressive. Measur.ing, we find that BG and GF wale4,100 and 1,875 pounds respectively.Now draw a polygon for joint(3) or (6) since there are hut two un-known forces at each joint. At (3) for instance, the unknown forces are those exerted by vh and gh^the known forces being the load… … Fig. 25. 174 STATICS 41 GBCHG is the polygon for the joint, and since BC acts down(see the polygon) CH acts up and HG down. Therefore, placethe proper arrowheads on ch and hg near (3), and record that thestresses in those members are compressive and tensile respectively.Measuring, we find that CH…
