The beam geometric properties of moment of inertia, area, and thickness are arbitrarily assigned values of 1.
Since the solution accuracy for a distributed mass system depends upon the number of master degrees of freedom
(MDOF) selected, twelve uniformly spaced longitudinal (axial) MDOF are selected. Results Comparison
