ee... that were a little harsh

Hmm. Let's guess he went for a good sized nut & bolt weighing half a pound together.

So, sat up on a bike with enough string to reach near the ground would be at least 4 foot of string.

Shall we say 4 revs per second? (Having just tried it with a power lead - much to her Ladyship's puzzlement).

Converting from medieval to metric...

250g swung on a 1.5m radius at 4 revs per sec = 250g at about 37 m/s.

That's a bit more force than as 28g at 300m/s, which is effect of shooting it in the head at point blank range with a musket!

An abattoir cattle bolt gun hits at about 75 m/s and the bolt on them isn't very big.

It certainly taught it not to attack animals with opposable thumbs and large brain cases in a predictable manner.

That's why I love this board. Good show old chap!

Have you accounted for the speed of the bicycle? If he was riding at about 5 m/s, we could determine the speed of the bolt as 42 m/s, and we all know what speed does to momentum. It's surprising the bolt didn't go straight through the dog's head and leave it's brains splattered across the floor.
