How much time did you spend on this event last year? We wound up working on it almost every day for 2 months before regionals and a bit less for states.

Information expressed here is solely the opinion of the author. Any similarity to that of the management or any official instrument is purely coincidental! Doing Science Olympiad since 1987!

Trajectory C

Postby rocketman1555 » July 2nd, 2008, 12:53 pm

i'm thinking about doing trajectory next year? does anyone from Div B have any ideas about how the device should work, like a catapult or slingshot, or any tips on how to build one

Well I personally am still milling over this but a thing to take into account is that rubber expands when heated so although rubber tubing sounds like a good idea it has it's drawbacks if left out in the sun.

which stinks here, because its always hot, i was thinking about asking the div b team in my area for their design, and then tweaking it to make it better

Well here's what the key is consistency the top 5 teams at nationals this year hit both pins but the top team hit both pins twice in the same spot. Number 2 you might like a device to help you aim. Number 3 the more options the better. That's all for now.

My teams trajectory design was basically two pieces of wood with rubber tubing between them. It worked quite well.

Yes, exactly like a slingshot, only bigger.

EDIT/ I believe I have a picture of the trajectory team using the catapult at states in my coaches classroom. I'll get it tomorrow and post the picture.
