OK, OK ;-)
A bit too easy. ;-) Here is another that is also easy, but might take at least a couple of minutes to solve.
The attached image is not to scale. The inner circle is half the diameter of the outer one, and the middle one is midway between them. As the dots travel around their respective circles, how many revolutions before they line up again?
rate of travel?
equal
You don't mention that the
circles run independently of one another. If that is the case then the reference mark is outside of the circles at the top where they appear at the start in the diagram. One revolution
Equal angular velocity?
Just kidding. The answer is 1/2 what I originally thought it was.
Sorry
I should have mentioned that the circles are independent.
clarification. ;-)
Play like the dots are little cars running on circular tracks all at the same speed, say at 22.467894654567 mph. ;-)
Re: OK, OK ;-)
large+1rev, middle=2rev, small =4rev
Re: OK, OK ;-)
I have the same answer for the middle one, but not for the other two.
No ;-)
Re: OK, OK ;-)
I get 3, 4 and 6 revolutions.
Re: OK, OK ;-)
That was my first answer. But I guess it depends on your definition of "lined up". At 1.5, 2, and 3 they are lined up, in a somewhat longer line.
