Rigid beam ABC is supported by a pinned connection at C and by an inclined strut that is pin-connected at B and D as shown. The strut is fabricated from two steel [E = 200 GPa] bars, which are each d= 77 mm wide and b = 17 mm thick. Between B and D, the bars are separated and connected by two spacer blocks, which are s= 30 mm thick. Assume that LAB = 0.75 m, LBc = 1.85 m, LcD = 1.60 m, P = 70 kN, The strut cross section is also shown.
