摘要
本文通过平面弯曲正应力分布图及静力平衡条件,推证了材力教材中对弯曲最大剪应力计算式中的Jz/Szmax 为一内力偶臂的几何含义及其应用。
Throngh the normal stress distribution figure and still equilibrium condition,it was proved that Jz/Smax at the equation calculating the maximum shear stress in bending members in mechanics of materials has geometric significance as one of inner couple arms.The application of Jz/Smax was discussed.
