A 2-kN.m torque \( T \) is applied to the solid cylinder made up of a hollow cylinder and an inner core as shown. NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part. Determine the percent of the torque carried by the inner \( 25-\mathrm{mm} \)-diameter core. The percent of the torque carried by the inner \( 25-\mathrm{mm} \)-diameter core is
