A stepped shaft ABCD ( \\( G=80 \\) GPa) consisting of solid circular segments is subjected to three torques \\( T_{1}=3.1 \\mathrm{kNm} \\), \\( \\mathrm{T}_{2}=2.3 \\mathrm{kNm} \\), and \\( \\mathrm{T}_{3}=\\mathrm{T} \\). Determine \\( \\mathrm{T} \\), which acts at point \\( D \\) (see figure) if the angle of twist at point \\( \\mathrm{D} \\) is \\( \\phi=1.8^{\\circ} \\). Give your answer in \\( \\mathrm{Nm} \\) to 1 decimal place.
