On the Stability of a Free-Free Beam Under Axial Thrust Subjected to Directional Control.
Abstract
This paper attempts to elucidate the mechanism of the loss of stability of a free-free beam subjected to a direction-controlled thrust. An adequate description of this basic problem does not appear to be available in the current literature. In contradiction to the claims made by several well-known investigations, it is shown here that (1) for a uniform beam under a constant thrust, the first nonzero eigenvalue represents an unstable bending mode, and (2) under directional control, the critical thrust varies with the sign and the magnitude of the control angle. Numerical data that have helped in understanding the problem are included.
