out axis through the centreof gravity, and S = cross-section. 86. Combined Bending and Torsion.—A shaft is oftensubjected to bending in addition to torsion, and in such a casemust be designed to resist both. The normal unit stress onthe cross-section at the extreme fibre from the bending momenton… … equal by § 154,-the stresses at the extreme fibre on a longitudinaland on a transverse plane are as shown in Fig. 43. (The plane TORSION. 8^ of the bending moment is at right angles to the plane of thepaper.) The principal stresses can be found by the method of§168. AB is the plane of…
