$2.$ A $14-$inch$-$long hollow brass rod $(1\mathrm{.}5-$inch outer diameter and $0\mathrm{.}8-$inch inner diameter$)$ is rigidly bonded to a $26-$inch$-$long solid brass rod $(2\mathrm{.}5-$inch diameter$)$ which is rigidly fixed to a wall. The righthand end of the hollow brass rod is free to move. The rods are subjected to two torques at the locations shown. $[$Brass properties: Modulus of Elasticity $=15{10}^6,$ Modulus of Rigidity $=[$:$5\mathrm{.}5{10}^6$
