  Static stability problem for axially compressed rotating nano-rod clamped at
one and free at the other end is analyzed by the use of bifurcation theory. It
is obtained that the pitchfork bifurcation may be either super- or
sub-critical. Considering the imperfections in rod's shape and loading, it is
proved that they constitute the two-parameter universal unfolding of the
problem. Numerical analysis also revealed that for non-locality parameters
having higher value than the critical one interaction curves have two branches,
so that for a single critical value of angular velocity there exist two
critical values of horizontal force.
