A truss element (beam with rectangular cross-section) is loaded in compression, as shown below.
a. Identify the plane in which buckling will occur first. Support your answer with calculations.
b. If instead of dimension 4a, the dimension along the z-axis is "b". find the ratio of ab such
that the beam is as likely to buckle in the xy plane as it is in the yz plane.
A truss element ( beam with rectangular cross -
