Aerospace Engineering > GATE 2013 > Column Buckling
In the steel structure (Young's modulus =200 GPa) shown in the figure, all members have a circular cross-section of radius 10 mm. Column BD is pinned at B and D. The support at A is hinged. The minimum value of load P at which the column BD may buckle in Newtons is approximately
Correct : 77000 to 78000
