A circular bar AB with ends fixed against rotation has a hole extending for half of its length (see figure). The outer diameter of the bar is d2 = 3.0 in. and the diameter of the hole is d1 = 2.4 in. The total length of the bar is L = 50 in.
At what distance x from the left-hand end of the bar should a torque T0 be applied so that the reactive torques at the supports will be equal?
