Figure Ha] shows a T m long cantilever concrete beam with a uniformly distributed load of w= 33 kam. The beam has a Tsection and is bolted to a steel plate {200 x 1:] mm] to form a composite section as shown in Figure 2 {b}. The modulus of elasticity is 25 GPa for the concrete beam and 20:) GPa forthe steel plate. The dimensions of the concrete sections are: a= 500, b= 3|] and c =70!) mm. {3} Sim plv supported TBeam lb} Cross-section Figure 2 3} Compute the moments of inertia with respect to the centroidal axis of the composite section. lu= x106 mm" Submit part Unanswered b1 Calculate the maximum stresses in concrete due to the loading. Gconcrete = MPa Please insert sign if it indicates the compressive stress.
