Question 3 Part a: For the section shown, determine the: • Maximum elastic Moment M Fully plastic moment Mfp ● Shape factor If loaded about the horizontal axis o, = 250MN/m²; E = 200GN/m² ● Part b: Determine the bending moment necessary to cause yielding to a depth of 10mm from the top and bottom surfaces. If after applying this load it is subsequently removed. What will be the residual stresses which will result at A and B when the load is removed? 80 40 B Yielded region 40 Fig. 3a 10 NA Fig. 3b NA
