Question:

Consider the idealized beam cross-section shown in the figure. The simplified piece-wise constant temperature-induced change

Consider the idealized beam cross-section shown in the figure. The simplified piece-wise constant temperature-induced change in Young's modulus, the channel beam cross- section no longer has an axis of symmetry. Within the top flange, E=0.8Eo and AT =2 To. Within the web, E =0.9Eo and AT = To. Within the bottom flange, E = Eo and AT-O. (i) Locate the modulus weighted centroid. (ii) Calculate the area moment of inertia about the z axis (iii) Determine the area product of inertia 20 8t 121 t, typ yo 8t *
