Abstract : The report summarizes the development of a general formulation applicable to physical engineering systems. An ndimensional energy space and an ndimensional energytime space are used to formulate lumped parameter systems in a manner which yields the equations of motion for the system by way of geodesics of the ndimensional spaces. Specific examples are included to demonstrate the formulation for electrical networks. The approaches presented are applicable to conservative and nonconservative lumped parameter systems. Results of the formulation are also applied to an electromagnetic wave in free space. A new approach to solutions of Euler's Equations is introduced and applied to a number of simple systems. A geometric interpretation of Riemannian spaces is presented to assist in relating physical system to geometric spaces. (Author)
