Just an interesting observation I’ve had, and if it’s not already a problem/theory/whatever, I think it should be. Also, it’s car related!
Imagine a wheel, made from a perfectly uniform material. Say it has eight evenly-spaced spokes. It’s perfectly balanced, and it’s possible to be made lighter by removing spokes. You can remove four or six spokes to keep it perfectly balanced.
But then take a seven-spoke wheel. It’s impossible to remove any spokes without throwing it out of balance. This is true of any prime number.
Basically, for any composite number of spokes, you can symmetrically remove any amount that will leave one of that number’s factors (excluding 1), and the wheel will remain symmetrically balanced.
Is this useful in the real world? No. Is it useful in math? Still not really. Is it an interesting way to look at prime numbers? Hell yeah!

If only math at school was car related I would have gotten much better grades...

Remove all the spokes!

If you had odd numbered spokes you could still machine down spokes without removing them. To keep the wheel balanced and reduce weight.

An odd number of spokes is symmetrically balanced as long as you use only one plane of symmetry. If the spokes were moveable, it could still be balanced and symmetrical on a single plane as long as the spokes were moved along the circumference to rebalance the wheel.
