Two thin rectangular sheets $(\backslash (0\mathrm{.}11\backslash$mathrm$\{$~m$\}\backslash$times $0\mathrm{.}38\backslash$mathrm$\{$~m$\}\backslash ))$ are identical. In the first sheet the axis of rotation lies along the $0\mathrm{.}11-$m side, and in the second it lies along the $\backslash (0\mathrm{.}38-\backslash$mathrm$\{$m$\}\backslash )$ side. The same torque is applied to each sheet. The first sheet, starting from rest, reaches its final angular velocity in $7\mathrm{.}4$ s $.$ How long does it take for the second sheet, starting from rest, to reach the same angular velocity?
