Electrical-Mechanical Systems Analogy

Mechanical	Electrical
Force (torque) $f$	Voltage $v_s$
Velocity $v=\dot{x}$	Current $i$
Mass (inertia) $m$	Inductance $L$
Damping $b$	Resistance $R$
Stiffness $k$	Reciprocal of capacitance $1/C$
${\omega }_n=\sqrt{\frac{k}{m}}$	${\omega }_n=\sqrt{\frac{1}{CL}}$
