And this is of considerable interest to those of us concerned with the
delivery of electric power through overhead lines.  If the wind can
make the strings of the aeolian harp vibrate, it'll also vibrate 3"
steel-cored aluminum power lines up on their steel towers.  The lines
can gallop, or they can vibrate at an audio rate.  Either one can cause
the line to break after a while.

Have a look at a high-voltage power line that is carried on steel
towers and held by long insulator strings.  Near the insulators, on
either side of the tower, you may see a little object that looks like
a pair of sausages laid along the line.  This is a vibration damper,
and the two sausages are iron, with rubber cores.

There is an annual conference on aeolian vibrations given every year by
one of the electric power engineering societies.
