How does the energy in a mace work vs a hammer or maul? Namely how you can seemingly greatly imcrease the end force by simply adding a flick of the wrist to your tool/weapon just before impact.
There's no free energy, so how does such a small wrist movement make such a difference compared to what you'd manage woth no wrist/joint.
with a maul or hammer, the length of the lever is more of less the length of the handle and most of the mass is There's no free energy, so how does such a small wrist movement make such a difference compared to what you'd manage woth no wrist/joint.
With a 'mace' on a chain, the length of the lever is the length of the handle PLUS the length of the chain. So greater acceleration and more force.

Having just taken the (full size) spare wheel and tyre out of my Rangie L405 I was shocked by how heavy the thing was. Must 6/7 stone. If I didn't replace it by how much would my mpg increase? At the moment I'm on about 25.5 mpg in a 4.4 diesel v8.
Knowing the science behind it, probably about 24.5mpg.And you'll definitely get a flattie while it's out.

I just flush the loo and hold the brush under the stream of water and then agitate it in the bowl. Rinse and repeat a couple of times. Job(bie)'s a good 'un.
Is that in the boys or girls CC? take your time to answer, get it wrong and you'll never hear the end of it
