Question: The truss is loaded by a vertical point force F . The rods of the truss have the same Young's modulus E and the second

The truss is loaded by a vertical point force F. The rods of the truss have the same Young's modulus E and the second moment of area I. The cross section of the rod is a circle.

Determine the rod forces in symbolic form.

Determine the symbolic expression of the vertical load F_crregarding to the buckling of the rod.

(Instruction: Look at which compressed rod gives the smallest vertical load value in terms of buckling)
