Q319. A thin-wall cross section is subjected an internal shear force \( V_{x} \) which is passing through the shear center of the cross section. C is the centroid of the cross section. On the \( A B \) segment, 1) Determinie the shear flow as a function of the local coordinate s. ( 7 marks) 2) Find the location and magnitude of the maximum shear stress. ( 4 marks) 3) What is the resultant of the shear flow? (4 marks) Given \[ \begin{array}{l} a=300 \mathrm{~mm}, t=7.5 \mathrm{~mm} \\ V_{s}=18 \mathrm{kN}, G=72 \mathrm{GPa} \\ t_{2}=175.5 \times 10^{6} \mathrm{~mm}^{4} \\ t_{y}=327.38 \times 10^{4} \mathrm{~mm}^{4} \\ I_{v}=60.75 \times 10^{6} \mathrm{~mm}^{4} \end{array} \]
