A cylindrical rod of length $\displaystyle 1$ m and radius $\displaystyle 4$ cm is mounted vertically. It is subjected to a shear force of $\displaystyle 10^5 \mathrm{~N}$ at the top. Considering infinitesimally small displacement in the upper edge, the angular displacement $\displaystyle \theta$ of the rod axis from its original position would be : (shear moduli, $\displaystyle \mathrm{G}=10^{10} \mathrm{~N} / \mathrm{m}^2$ )
