Question 3 - (12 marks) The cross section shown in Figure 3 is subjected to a bending moment of 850 Nm. For a 0 value of 30° determine the following: - (i) The stress at each corner of the section at A, B, D and E and at the neutral axis (6 marks) (ii) Sketch the resultant normal stress distribution indicating the variation between B, D and E and the neutral axis. points A, (4 marks) (iii) Define the location of the neutral axis relative to the corner points. (2 marks) 250 mm B D 125 mm Figure 3 125 mm E 0 M = 850 N-m Question 3 - (12 marks) The cross section shown in Figure 3 is subjected to a bending moment of 850 Nm.
