hello all, first post here so don't bite. if a perfect strut was compressed by an 2 imaginary point forces acting exactly on its centroid, and ignoring outside effects, would it bend laterally, and why so? when I say perfect, i mean ignore all consequences of practicality, ie. the alignment is precise to the eg. atom, and the bar is of impeccable geometry along its length. i was having a debate about this for at least 20 minutes with someone, and I saw no good reason why it should (ignoring material failure for the moment), since the point forces acting on the centroid produce no moment/horizontal component to cause the strut to bend in such a dramatic manner.
