Explain the phenomena of mechanical resonance and damping

A) Explain in your own words what is meant by mechanical resonance of a structure.

B) Undertake your own research and describe real-world systems where mechanical resonance has caused problems and outline the measures

that were taken to prevent it. You should aim to write somewhere in the region of 600 words in total.

C) Explain what is meant by damping and why it is incorporated into a structure. What are the design implications for damping?
