A steel rod like the one shown in the attached picture is fixed from one side and increasing amount of torsion is applied on the other side. Eventually, the rod breaks. Now it will obviously break from one of the two chamfered locations, where the middle portion of the rod with the smaller diameter increases to turn into the larger diameter ends, due to the stress concentration effect. But from which of the two sides will it break; the fixed end or the movable (rotating) end?
