Quastion?
A rectangular beam will be used for the beam in Question 1. The cross-section is shown in Figure Q2.
Sketch the AC beam and show the locations where the bending stress will be maximum [03 marks]. Determine the maximum tensile and compressive stresses acting on the beam [05]. Draw the bending stress variation along the cross-section for each case mentioned in part 2(b), indicating critical values [01 mark].

In order to optimize the design, we decided to reduce the allowable bending stress capacity. The maximum allowable tensile and compressive stresses are 12 MPa and 11 MPa respectively [10 marks].
