RedCloud shivers quite often, but it only has one frequency of
shivering, the shiver is always the same, just different durations and
strength.

Anyone elses boat shiver?

Joe


If your boat was a thin rod it would have only one modality of
"shivering" and one fundamental frequency of resonance. Your iron bucket
is a complex structure with multiple modailities and a complex of
harmonics.

Thanks, that's good info. I had always assumed rust was just too soft to
have any harmonics at all.

Rust is not strongle coupled to the mechanical structure. That shivering is
good for knocking asny rust lose.
