A circular bar AB with ends fixed against rotation has a hole extending for half its length the outter diameter of the bar is \(\displaystyle{d}_{{2}}={100}{m}{m}\) and the diameter of the hole is \(\displaystyle{d}_{{1}}={80}{m}{m}\). L=1250mm.

At what distance x from the left hand end of the bar should a torque \(\displaystyle{T}_{{o}}\) be applied so that the reactive torques at thesupports be equal.
