o excess), thelongitudinal unit stresses between the particles will vary as thelengthening and shortening of these fibres, that is, as the dis-tance from the point of no stress. Hence, at any section, thedirect stress is uniformly varying, with a maximum tension on 56 STRUCTURAL MECHANICS. the… … Fig. 21 63. Neutral Axis.—The arrows in Figs. 20, 21 may be takento represent the unit stress at each point of the cross-section,varying as the distance from the plane of no stress, and constantin the direction z. To locate the point or plane of no stress orneutral axis for successive sections: Let…
