Figure Q3 (a) shows a simply supported beam ABC subjected to a point load, P. The cross- sectional area of the beam is shown in Figure Q3 (b). The yield stress of the material is 300 MPa and the material is assumed to behave linearly elastic-perfectly plastic. If the whole flange of the cross-section has become plastic, determine; a) b) c) d) The position of the new neutral axis The depth of the web on the bottom surface that has become plastic The magnitude of bending moment at point B The magnitude of load, P B 4 m Figure Q3 (a) Flange Web 60 mm 20 mm Figure Q3 (b) [10 marks] 20 mm 100 mm Figure Q3 (a) shows a simply supported beam ABC subjected to a point load, P.
