Q4. Two equal and opposite couples of magnitude M = 1x kN-m are applied to the channel-shaped beam AB, where x is the last digit of your student number (e.g. M = 18 kN-m if your number is 12345678A). Observing that the couples cause the beam to bend in a horizontal plane, determine the stress (a) at point C, (b) at point D, (c) at point E; and (d) among the four materials given in the table, is there any one that can be safely used as the beam to sustain the load? If yes, identify the [10 marks] material no. 100 mm 24 mm -30 mm 150 mm B 24 mm Material Allowable stress in tension Allowable stress in compression #1 90 MPa 90 MPа #2 80 MPа 150 MPa #3 150 MPa 80 MPa # 4 50 MPa 150 MPa Q4.
