Abstract
This article extends a procedure that has been used to discretize a static physical system following the assumption that a continues flexible beam can be replaced by a system of rigid bars and joints which resist relative rotation of the attached bars. This procedure is called "discrete element response of beams". The object of this paper is to present and formulate a new, simple, practical and inexpensive approximate technique for determining the response of beams with different boundary conditions, carrying a moving mass on a tensionless elastic foundation, which usually ends in very complicated nonlinear differential equations.
