(a) If the beam A-D has a rectangular cross section as shown in Figure. 3.1 - (i), determine the optimal position (x) of the two supports so that the beam A-D can carry the largest load without failure of the structure. Also, find the corresponding maximum allowable q. Take h=300 mm and b=22 mm. (b) Now reconsider the beam A-D with an asymmetric "I"-shaped cross section in Figure. 3.1 -(ii). If the magnitude of the distributed load q is equal to 137 kN/m and the overhang x is equal to 137 mm, find the maximum compressive and tensile stresses in the beam. Take h-30 mm, h2-240 mm, and h3-30 mm for heights, and bi=40 mm, b2=22 mm, and b3=60 mm for widths. Is the beam safe with this configuration?
