Sorry, guess some ASCII art would've helped:

The arrow shaft is laid down on 26" centers:


on top of a lever, the small end of which is pushed down when a 2 lb. weight is laid upon the shaft.

I need to draw a scale which shows where the pointy end is when the rounded end is pushed down a certain amount:

-------------     /        ------------

If someone knows the names of the formulae involved in calculating how much the large pointy end moves based on the small rounded end being pushed down, I'd be very grateful.
