What Myth would you want to see busted?

It will still be 1000, you aren't spinnin the pistons in the opposite direction at 1000rpm.
You scenario of cancelling forces would however work on an electric motor.
As part of what the motor workings is attached to the casing. The permanent magnets. So in this case the shaft would have a zero speed, relative to ground. But a relative speed to the motor casing of 1000
 
Are you guys enjoying the debate or is this 'SOMEONE ON THE INTERNET IS WRONG!' territory? I've nothing to add, I'm simply curious.

It's also an amazing and amusing read, for what it's worth :)

No your spinning the engine block attched to the helicopter.

That (when the engine is firing) is 'attached' by explosive force to the pistons.

No free moving element

And which way are you rotating the pistons, they aren't in the same direction as they are horizontal, not rotational. The free moving elelement is the crankshaft.

I can't belive this. The pistons are acting around a common rotational centre, the crankshaft, which IS being rotated in the opposite direction.

The motor comparison is wacko tbh. Lots of what makes an engine works is also attached to the casing.

I'm going to give up now. I really don't know how to make it any simpler. You stick to what you believe buddy :rolleyes:

I'm going for a drink :D
 
A crankshaft surely cannot be free moving by definition, as that would require it to not be attached to the pistons?

If a crankshaft was a free moving element, an engine wouldn't work :/
