Balance of forces in Mass, spring, damper system:





Balance of voltages in RLC circuit:



Comparing two balance equations, we get below relationship between two systems.







Mechanical Force Electromotive force
Velocity Current
Mass Inductor
Reciprocal spring constant Capacitor
Damper Resistor
