Read OP's title.
It is trivial to calculate arc length. But the equations you wrote are wrong. It should be Z/360 instead of 360/Z and Y/360 instead of 360/Y.
A, B and C are constants. It can be proven using trig that theta=-80 for all positive real values of A, B, C that make the three equations true. In other words, for the given conditions, theta must be equal to -80 for all three equations to be true, if theta is not equal to -80 at least one...

Why do you think the other posters meant "the toolbox has a shorter impact time and thus a higher impulse"? Unequal forces can produce equal impulses.
The lack of comprehension shown in this thread is pretty sad. The video and physorg article clearly state force from ultrasonic equipment is used. Even a first grader can read it and understand. Blowing air is not used or mentioned in video or article. Perhaps stuff like this is too...
Are you saying the podium dude who says "We are the premier engineering and science institution in the world" is not from MIT?
A girl in the vid says "I'm not a electrical engineer, I'm a mechanical engineer."
One wire no current girl seems to be confident in her answer.
This appears to...
