TASK 3 250 180 14 I 30 24 Weld 450 A compound girder consists of a steel joist with steel plates welded onto each flange as shown. If the ends are simply supported and the effective span is 10 m, what is the maximum UDL which can be supported by the girder? [kN/m] Allowable longitudinal stress in plates = 110 MN/m² Allowable load in shear for each weld = 60 kN/m Allowable shearing stress in web of girder = 75 MN/m² Note: 1.0 MN/m² = 1.0 N/mm² 50

Hand written and clean solution please

2. Calculate the internal forces in the bar GF and GD in a roof truss as shownbelow. For each bar, indicate if the internal force is tensile or compressive. Usethe section method (snittmetoden). Point A has simple support and D has rollersupport.
