1. A W150×18-shape rolled-steel beam is to be used for the structure shown in the following figure. For the rolled-steel, the maximum normal stress [0] = 170 MPa and the maximum shear stress [7] = 100 MPa. Knowing d = 153 mm, tw = 5.8 mm, 1₂ = 9.2 x 10-6 m², S₂: = 1.2 x 10-4 m³, determine the allowable load F acting at the middle of the beam. A 3 m F Į H tw bf tf 3 m B
