On the Equations Governing the Free and Forced Vibrations of a General Non-Conservative System

Abstract
An expression is derived for the steady forced response of a system governed by the equation in which A, B and C are real but not symmetric. The theory is effectively an adaptation and exploration of previous work by Woodcock (1)‡. His studies were published in the ‘Hamiltonian’ form, while in the present paper the Lagrange approach is used.
