To change tracks, bendable switches are used which consist of a continuous steel beam which is elastically bent by means of electro-mechanical setting drives.

若要改道，可采用曲性道岔。这些曲性道岔由无缝钢条组成，通过机电制导装置，使其柔性弯曲。

When box beam is bent, the assumption that the section is plane is not satisfied and the shear lag is produced.

箱形梁弯曲时，平截面假定已不能满足要求，产生剪力滞效应。

This exploits one of the predictions of Einstein's general theory of relativity: that the path of a beam of light (which is a straight line in empty space) is bent inwards by the gravity of a massive object.
