“关于截面周边可变形的梁在一般情况下有没有扭?中心或挠曲中心”的问题,引起了有关同志的讨论。下面发表的钟宠仁同志来信,是从实际应用的情况提出了自己的看法。本刊亦就梁的扭转中心及分析方法等方面提出一些初步意见附于刊后,供进一步讨论时参考。 “The question of whether there is any twisting center or flexing center under normal circumstances” about the deformable beams around the cross section has drawn the discussion of the comrades concerned. The following letter from Comrade Zhong Petren has put forward my own views on the actual application. The journal also made some preliminary comments on the beam’s center of reversal and analytical methods, which are attached to the journal for further discussion.
