Machine......
the net energy of the system is independent of the distance............but thats not the same as the energy imparted to the projectile.
take a slingshot with only one band on it............and pull that ban off to one side.....and let it go.....that is where the energy goes....and That is exactly the same as the F Cos( theta) component of the angled band......
like i said before, that energy is transmitted back into the slingshot and into your arm.......
the reason you dont notice it is because you have 2 of them acting in opposite directions.
when you have an angled band, not all of the energy is going into throwing the projectile.
now joerg, i just want you to know that none of this is a criticism of your work, you know what you are doing and you designed your crossbow the way you did for a reason.....this is all simply a response to Glistam's question.
