St patricks day

I know that we all think that there's a pot of gold at the end of a Rainbow, But most of the time you never get to the end. If you could, I would definately think that it would be moved by machines. The pully would be an easy one for Lepricauns to use, they can't be seen when they move it. I don't believe in Lepricauns, but it's mostly because I haven't seen one.

The relation ship between input and output force or distance , is that the input force/distance is how much you put into it. The output force/distance is what you get out of the input force/distance. You can't just have one. The differences between the short and long wedges mechanical advantage is that the longer ones have a greater MA, and the short ones have a littler advantage. In short, it takes less effort to use the bigger wedge and more effort to use the smaller wedge.
