Re: Sodaplay: Tacoma Narrows resonator

it was an aeolian oscillation driven by a steady wind

Having just used this in class as an example of resonance and wanting to
be better educated, I am puzzled by these statements. So I ask some
questions:
1. If one tuning fork causes another to begin vibrating, is that
resonance....I think so.

2. If I sing near such a tuning fork and part of my melifluous voice (;-0)
causes the fork to vibrate can I cite resonance?

3. If a steady wind stimulates wire cables to vibrate in an assortment of
modes, is it possible for one of those frequencies to stimulate
sympathetic vibrations in an neighboring oscillator?

4. What mechanism started and supported the oscillations of that bridge?
