well as the work of the externally applied force P. The beam remains stable
while the energy of beam deformation is greater than the work of the force P.
The force-displacement diagram (or, in the general case, the control param-
eter versus state of the system diagram) is an important tool to study the
stability of the system. One can observe that there are several types of the
transition to instability (the loss of stability of the equilibrium state). These
may involve the formation of new equilibria, the jump to another state of
the equilibrium, or just the absence of the state of equilibrium ...
