OT: need Science Olympiad help

As of last weekend, DD1 has been signed up for a new event for the State tournament - Trajectory... She is also doing Road Scholar and Oceanography Her team won District and Regional! Whoo hoo!!!!

has anyone here done this and have any pointers? The paperwork she brought home is rather vague on the construction, her teacher has not been able to stay after to help this last week and she has a week and a half to make a model to see if she can really enter or not. Basically it says Teams will design, construct, calibrate and operate a device capable of launching a projectile into a target using energy provided by nonmetallic elastic solids. The device must fit inside an 80cm cube. It must be launched remotely but not by radio signal. The projectile will be a pliable, hollow ball btwn 3 and 9 cm in diameter. The target areas will be between 2 and 8 meters from the launch area at two different levels. I think that sums up most of it...Altho I do know that the force has to come from the elastic solid (ie no stored energy).

Her teammate is coming over tomorrow to work with her.

found this

DH has a huge crew coming over to work on model rockets tomorrow too. lol

If it is any help Kellie, the historical name for that weapon is 'Trebuchet' (tre-boo-shay - the 'e' is short as in 'trellis'). I had a quick look on Google for you, and there is loads of information there - how to make things etc. Could be fun. The release mechanism will be fun! What a great enterprise >g< .

actually they said we could make a catapult but not a trebuchet b/c the trebuchet uses gravity instead of using energy provided by nonmetallic elastic solid(s)

I am still researching. Think the remote trigger device may pose the most trouble at first. Aiming later on!

Not the ones I've seen, but I certainly haven't seen them all!! But, perhaps they are more counter balance than 'latent'? energy. Fascinating anyway. We had a TV series a couple of years ago with modern teams making ancient weapons with old drawings and materials. Most interesting. . In message , Kellie J Berger writes
