Within the framework of linear elasticity, we show that any displacement of a straight rod is the sum of a Bernoulli–Navier displacement and two terms, one for shearing and the other for warping. Then, we load a straight rod so that bending and shear contribute the same to the rotations of the cross-section.

通过伯努利-纳维位移分解杆位移。应用：杆的剪切加载

在线性弹性的框架内，我们证明直杆的任何位移都是伯努利-纳维位移和两项的总和，一项用于剪切，另一项用于翘曲。然后，我们加载直杆，以便弯曲和剪切对横截面的旋转做出相同的贡献。
