gid 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 fabricated from two steel [E = 200 GPa] bars, which are each d= 75 mm wide and b = 16 mm thick. Between B and D, the bars are parated and connected by two spacer blocks, which are s = 27 mm thick. Assume that Laß = 0.85 m, LBc = 2.05 m, Lcp = 1.70 m, P = 70 N. The strut cross section is also shown. Determine the compression force in strut BD that is created by the loads acting on the rigid beam. the slenderness ratios for the strut about its strong and weak axes. the minimum factor of safety in the strut with respect to buckling.
