Question

stresses at it cornics A 2 For the beam section (shown in Fig. 2) calculate and plot shear stresses in the flanges and webs when a vertically downward shear force of 25kN is applied at the section. Also locate the shear centre for this42. section 3 A W-section, used as a column, supports an axial load of 280kN and an eccentric load P at e-200 mm along the minor axis. Determine the maximum allowable value of P based on AISC equation when the length of the column is (a) 3m and (b) 4m. Assume the column is fixed at the base and free at the top. Take σ,-350 MPa and E-200 GPa 、12 ( Section Properties are A-10200 mm2, 126x 106 mm4, S,-928 x10 mm1111mm,1,43.1x10 mm338xmm, and r 65mm. 4 A thick cylinder having outside radius of 160mm and wal thickness of 60mm is subjected to an internal fluid pressure of 80 N/mm2 and an external pressure of 12N/mm2. Calculate maximum and minimum 3(C3 3 intensities of tangential and radial stresses in the cylinder wall and plot the variations across the section go 160 10 80 (centriod 不一-) 80 8 o = 90.57x10 32 Fig. 1 Fig. 2
