Question 1 A 150 x 75 x 12 angle shown in Figure 1 is connected to a gusset plate using a E70XX 10mm weld. Using S355JR steel do the following. 1.1 Calculate the design tensile resistance of the angle. (15) 1.2 If the transverse weld is removed calculate the tensile resistance that will govem the design. (5) Note: Check all possible fallure modes 145 mm 150 mm 260 mm
