Free Damped Vibrations

Free vibration is a type of vibration in which the external force is removed after giving the initial displacement to a body/system. In other words, in this type of vibration, force is applied at the initial displacement of the system, and after the initial displacement, force is removed, and the system vibrates at the natural frequency.

3. The Duffing equation describes a nonlinear oscillator with a nonlinear spring (energy storage component) and possibly a damping component: equation. m i d²x dt2 2 +c dx + kx + εx³ = f(t), where c, k and & are constants. dt Chow that the Duffing equation fails to meet the requirements for a linear operator Develop the general solution for the case where & =0 and f(t) = 0, and the initial conditions are x(0) = xo, dx/dt(0) = vo; and show why the approach will not work for the case when �. For the case where c = 0 and f(t) = 0, the homogeneous DE falls into one of the categories of second order ODE's that can be integrated using a transformation of variables. Using that transformation, carry the solution process as far as you can.
