should assume both materials exhibit linear elastic behaviour. The concrete cracks in tension at 5.75 MPa. The RHS is used as a beam, bending about the horizontal axis. Question 17 Question G1 Transform the material to be all steel. What is the second moment of area of the transformed section about the horizontal centroidal axis (in mm²) ? Ignore the effect of the corner radii between the flange and web (ie assume all intersections are perfect right angles). You will not be able to enter your answer using exponential powers of 10 - eg if the answer is 3.456 x 106 you would need to enter 3456000. Question 18 Question G2 What positive bending moment (in kNm) would make the concrete crack in tension? Question 19 Question G3 What is the maximum tension stress in the steel (in MPa) when the concrete cracks? Question 20 Question G4 Now consider a different bending moment that creates a maximum tension stress of 15 MPa in the steel. What is the maximum tensile strain (in microstrain) in the concrete?
