The truss ABC shown in the figure supports a vertical load W at joint B. The distance between supports is 7.0 m and joint B is restrained against displacement perpendicular to the plane of the truss. If each member is a slender circular steel pipe (E = 200 GPa) with outside diameter 100 mm and wall thickness 6.0 mm, what will be the critical value Wcr of the load in kN? (Answer up to the nearest integer)
    Correct answer is '203'. Can you explain this answer?

    Truss ABC with load W
    Steel pipes AB and BC:
    E = 200 GPa, L = 7.0 m, d2 = 100 mm, t = 6.0 mm
    d1 = d2 – 2t = 100 – 12 = 88 mm
    For lengths of members AB and BC, we use the sine law as,
    Buckling occurs when either member reaches its critical load. Critical loads are,
    Free-body diagram of joint B:
    Solving the two equations, we get
    W = 1.7368 FAB, and W = 1.3004 FBC
    Based on member AB:
    Lower load governs. Member AB buckler.
