I would think you'd want it to be at a height so that when the arm is perfectly vertical, the CW just barely doesn't touch the bottom of the device. Any higher and the counterweight hits during launch, wasting energy, any lower and you waste energy by not using all the height allotted to you in the rules.For a FAT trebuchet, would it be better to have the wheels up high on the arm, close to the counterwieght, or down lower?
I'm just wondering because I'm about to start working, but I don't know which would give it more launching power.
Not all of them, but some of the OBB threads on STC:Thanks, but I didn't see anything in the OBB. I guess it'll be a matter of trial and error, which I think this event is a lot of.
Does anyone know how wind may effect the event? Will it be held indoors? Or does the wind usually not play a large factor in this event?
There is no single ratio of these variables that will work over a range of projectiles and falling masses. If you want to make the device work throughout the range of possibilities than you need to have the ability to adjust these ratios. The issue then becomes the huge amount of testing neededThe ratio between short and long arm length, wheel position, and sling length are what makes this event a challenge. It's hard to say what will work best for your individual design. You may want to try to read over any previous (archived) posts. They have some good information.
