Web and flange are weld together and the maximum shearing stress that can be sustained in the weld area is 250kPa. i. indicate the location of beam cross-section where the shearing stress is a primary concern when it is subjected to loading with the help of sketch. ii. analyze if the beam would fail under shear at section a-a due to the applied loads. Given centroid y is located at 36.25mm from the base of the beam. 8 kN 15 kN/m 20 mm 70 mm B D B 20 mm 50 mm -1.2 m- -1.2 m- 0.3 m' 0.3 m Web and flange are weld together and the maximum shearing stress that can be sustained in the weld area is 250kPa. i. indicate the location of beam cross-section where the shearing stress is a primary concern when it is subjected to loading with the help of sketch. ii. analyze if the beam would fail under shear at section a-a due to the applied loads.
