Coin Flip Task

[Unome]

See rule 4.b.x for details.

Since the quarter has to go from heads to tails, a single half-rotation would probably be best for consistency - anything more makes it more probable that the coin will land with the wrong side up.

Would using the lever system be sufficient to flip the coin or would it be better to have a separate and more precise action to flip the coin

So long as it works consistently, I'd say to go for it. It may be in your better interest to take a more controlled approach with a motor, or a calibrated servo. The hard part seems to be ensuring that the coin consistently airborne at a point during the flip (assuming the jump is short, which would be favourable).

What is meant by airborne? Can I simply drop the coin off an edge to flip it so long as it doesn't touch anything as it flips? Or, does the coin have to be forced upwards by something like a lever?

Per the ES at the Centerville Coaches Clinic, the coin must be completely in the air (not touching anything besides air) at some point during the flip.

Yes because it would be in free-fall after falling off the ledge.

Good idea. Dropping it off a ledge seems more reliable than a flipping machine.

People keep coming up with the same ideas as me

What if I use a lever to force it downwards? Basically I'm using a third class lever where the coin is the load and having the lever rotate from horizontal to 135 degrees. So the coin is technically flipping sides while still in contact with the lever, but after the lever stops the coin is airborne before it hits the surface, which means it went from heads -> tails in the action while being airborne at some point...?

This is unofficial but Patrick Chalker (national ES) said that the above action is allowed at the coaches clinic. This was one of his recommendations if my coaches are to be trusted. Apparently the flip does not have to occur while the quarter is airborne.
