My personal spinner that is defined.
Before we printed our whole spinner we printed the hole sizes to make sure we had the right sizes for the coins.
This is the printer that we printed our fidget spinner on.
My personal spinner on onshape.
To test the spinner we put the spinner on a skateboard truck that was on a board. We secured the spinner with a nut on the end. We lifted the arm until the arm was all the way up and then dropped it onto our spinner. We started the time when the arm hit the spinner and when it stopped spinning.
(This spin represents a 1 minute spin it isn't actually 5 seconds)
Is there a relationship between the weight and the time?
Yes weight is important to a spinner. Not having enough weight can cause your spinner to go really fast but then it's slows down just as fast. Since there is no weight there isn't anything pulling the spinner around. Having too much weight will make it very hard to get the spinner going at a good speed. Another big thing with weight is where you put it. You want your weight as far from the middle as possible (so it can fit in your hand), doing this will maximize your centrifugal force. Having your weight in the middle will have none and your spinner won't spin as long.
Is there a correlation between the number of spokes and time?
Yes and no. Adding more spokes off of the spinner can be beneficial. If you add weight that helps it spin longer and faster then it is good. You want your spinner to be heavy. But then you can add dead weight. Dead weight is weight that does nothing but hurt the spinner. Dead weight is like adding weight in the middle or adding too much weight.
Is there a correlation between the height of the trial and the time?
Yes. The higher height of the trail means the harder the arm will come down. If the arm comes down harder than the spinner will go faster. The lower the arm the less force it will come down with, causing the spinner to not spin as long.
