Truck wheel reverse illusion: original 6deg pattern

Alex from the ClockWork Orange?

Daughter in high school, she was temporarily a huge fan of munching away at eggiwegs, and lomticks of toast and lovely steakiwegs, while givin ya one in the yarbles, if ya have any yarbles.

mmm... eggiwegs I would like to.... ¡¡SMASH THEM!! xD

Sorry for being "stupid" sometimes. It's hard to describe thoughts in 500 chars on foreign language. =P
Seems, like I saw description of purpose of this "research unit"...or it's just personal intention?

Yes, I've been calling it "false strobe-effect."

Personal projects, see "Science Hobbyist," amasci com

While driving on the highway, I fortunately observed the "reverse wheel effect" in direct sunlight. The hex-nuts on a large truck wheel contained a pattern which rotates backwards. The cause was obvious: flashing of the flat facets of the nuts.

But why would a truck driver bother to align the wheel nuts so carefully?

Experiment shows that it occurs accidentally when changing a flat tire, whenever all nuts are tightened to similar angle.

Example, You work in workshop with milling machine, and with certain speed of rotation sence of "no motion" appears. To exclude accidents need eliminate flicking. When I'm studied. There was one laboratory work to determine light flicking speed (on FL. lamps). We used fan with bend blades, changing speed we can catch "no motion" moment. Look the same...

Outdoors? IN SUNLIGHT?

For decades, eyewitnesses have been reporting a "backwards wheel" illusion seen in bright sunlight. The effect is genuine and quite simple. It's produced by aligned nuts on vehicle wheels. It's a non-stroboscopic mechanism which creates a backwards wheel illusion.

You're only talking about something entirely different: the well-known fluorescent light artifact.

Also: watch the video closely.

The pattern in the lug nuts *always* moves backwards, and it's drift-rate is proportional to rotational speed.

Strobe effects behave entirely differently. Instead they essentially are "beat notes," and there's a special speed which causes the apparent motion to halt. Slightly changing the speed will cause the pattern to drift either forwards or back (rather than exclusively backwards, like the lug-nut facets phenomenon.)

Oh. Sorry for missunderstanding. This strobe caused by flicking of reflected light of each side of nut (You set up them precisely to slow down rate on high speed of rotations). The reason of it is reverse motion of reflection. (each nut make rotation in same direction as disk. Imagine that nut it's a 6 mirrors composed together. Than each side rotate in same direction as disc. But if I'll rotate mirror - image in it will move in opposite direction, like world rotate around mirror.) Am I right?
