"Atreb estimated that I would throw an 8 lb pumkpin 943 feet - I actually hit 927 during competition, but that was into a slight headwind. I'd say it's pretty accurate."
-- Chris Gerow, Winner of the 2000, 2001, 2002 and 2003 World Championship Punkin Chunk, Trebuchet division.
Q: What's the best way to learn about trebuchets?
A: Build a lot of them!
What's the easiest, cheapest and safest way to test your theories about trebuchet mechanics? Use a trebuchet simulator!
What is ATreb? "A" stands for accurate, and "Treb" is short for Trebuchet. This is by far the most accurate trebuchet computer simulation you can get!
Engineered and programmed by Les Scholz, this simulator goes beyond just lengths and weights! You can add the effects of air drag, friction, do stress analysis on your arm, sling, pin, axle... and work out all the finer details of your trebuchet design before you even buy a single piece of lumber. It also includes a metric conversion calculator, release pin optimizer, and you can save hundreds of design parameters and simply load them from disk to work on different projects at the click of a button.
