In theory that means the effect of resonance in a system with mechanical vibration?
Sorry, your question is hard to interpret. Could you please post more details, including the problem definition, any relevant equations, and your attempt at a solution?
The equation and solution I found. I wonder what is resonance and what are its effects
Resonance is the gradual increase of the amplitude of the wave when the forcing term has the same frequency as the natural frequency.
