A circular bar \( A B \) with ends fixed against rotation has a hole extending for half of its length (see figure). The outer diameter of the bar is \( d_{2}=3.0 \) in., and the diameter of the hole is \( d_{1}=2.5 \) in. The total length of the bar is \( L=50 \mathrm{in} \). and \( T 0=97.4 \mathrm{kip} \)-in. Question 1.4: What is the maximum shear stress in the solid segment when the torque is applied at the location determined in Question \( 1.3 \) above ? [enter solution in in - 2 decimal places].
