Lumped Electromechanical Elements In what follows we review concepts of circuit theory and derive lumped parameters in a general way to include electromechanical coupling terms. We then review the concepts of rigid-body mechanics. Electromechanical coupling is discussed in Chapter 3. 2.1 CIRCUIT THEORY The mathematical description of a circuit essentially involves two steps. First, we must be able to describe mathematically the physical properties of each element in the circuit in order to produce expressions for the terminal properties of the elements. Second, we must combine the equations for the elements in a manner prescribed by the interconnections of the elements. This step is performed by using Kirchhoff's laws and the topology of the circuit.* Thus we need only to generalize the description of circuit elements to include the effects of electromechanical interactions. Conventional circuit theory is the special case of stationary systems in which quasi-static electromagnetic field theory applies. All the concepts of
