Flutter Induced By Dry Friction
It may seem surprising that aeroelastic flutter is a phenomenon sharing similarities with instabilities due to friction. This was recently experimentally discovered by Bigoni and Noselli (2011), who have produced a follower force through dry friction at the contact between two sliding bodies, see the animation on the right and watch a movie for more details.

“Scarlet, and blue, and snowy white,
The guidon flags flutter gaily in the wind.”
—Walt Whitman (1819–1892)
“Few can be induced to labor exclusively for posterity; and none will do it enthusiastically. Posterity has done nothing for us; and theorize on it as we may, practically we shall do very little for it, unless we are made to think we are at the same time doing something for ourselves.”
—Abraham Lincoln (1809–1865)
“Have you not a moist eye, a dry hand, a yellow cheek, a white
beard, a decreasing leg, an increasing belly? Is not your
voice broken, your wind short, your chin double, your wit
single, and every part about you blasted with antiquity? and
will you yet call yourself young?”
—William Shakespeare (1564–1616)
“The admission of Oriental immigrants who cannot be amalgamated with our people has been made the subject either of prohibitory clauses in our treaties and statutes or of strict administrative regulations secured by diplomatic negotiations. I sincerely hope that we may continue to minimize the evils likely to arise from such immigration without unnecessary friction and by mutual concessions between self-respecting governments.”
—William Howard Taft (1857–1930)
