bout b is thesame as the moment of the forces , and R about C,the sign of our second term is positive.* The first memberis therefore negative ; that is, the stress in AD acts left-handed about C. AD is then in tension by the amount —• To get the stress in CD take centre of moments at A. The sum of… … stress - AG Fig. 57- the compressive stress in CE = DH The stresses in all the members may be found by further application of this method.The sections must always be so chosen as not to cut more than three pieces whose stressesare unknown. If a fourth piece is cut whose stress is known, the moment…
