The outward shift of a plasma column in a toroidal system is calculated using the ideal hydromagnetic equations for a stellarator model. At a critical value of the plasma pressure this outward shift becomes infinite. This is the pressure for which the equivalent straight system is marginally stable against the type of displacement induced by the toroidal curvature. The very close relationship between equilibrium and stability problems is thus illustrated.
