Re: Catapult?
[smileing] Whenever someone comes out and says that something 'cant be done' at this point in the design cycle, sure enough when you get to your 1st regional you will find someone who found a way.
If a pneumatic shooter can launch ten balls at once, how fast does it need to cycle? how many times per match do you think you will be launching 10 balls at once?
The balls dont weigh 10 lbs each, so you are not pushing or lifting a 100 lb mass.
How do you get all that air in the cylinder 'all at once' ? You dont: you block the cylinders motion halfway down it length, precharge the cylinder up to 60 psi, pull the blocking pin out of the way and POW! its like a garage door spring with 180 lbs of force being released.
How much will ten balls weigh? with 180 lbs of force behind them what does F=MA tell us?
