Steel beam has a double T-shaped profile \( N \). 14. The maximum tangential stress in beam cross-sections \( z>0 \), must be determined, if the beam is loaded with concentrated force \( P=2 \mathrm{kN} \) and \( \mathrm{L}=3 \mathrm{~m} \) The cross-section second onder moment of area (axial moment of inertia) \( I_{x}=572 \mathrm{~cm}^{4} \). Static moment of half cross-sectional area \( S_{x}^{*}(0)=46.8 \mathrm{~cm}{ }^{3} \) and the thickness of the vertical wall of the profile is equal to \( 4.9 \mathrm{~mm} \)
