Question

3) (35 pts) A L-beam has the cross section shown. A moment M acts about the x-axis which passes through the centroid of the section. Determine the angle the neutral axis makes with respect to the +x- axis. Sketch it on the cross section. Given the design flexural stress limit is 100 MPa, determine the maximum allowable moment which can be applied. You only need to evaluate the stresses at points A, 8. Helpful hint: Remember to change the sign of your flexural stress limit depending on if you are evaluating the tensile or compressive stress limit. Ix 2.61(10) mm, Iyy7.24(106) mm,Ixy 2.54(106) mm. Note, the sign of Iny is based on the coordinate system shown. 25.1 mm max 50.5 mm 102 mm is the design limited by the tension or compression stresses 152 mm
