They used torsion and non-torsion catapults because it had better strength and it could go a lot further. The way it goes straight is that when the most force is released when the catapult is straight upwards and it flings out of it.fallon and alex were in my group. alex is doing blueprints and fallon is doing calculations. on the target we hit all 40s. ]]> 2018-01-25 20:32:02 UTC https://padlet.com/emilygilley/8mroyblhtzhp/wish/224865197 emilygilley https://padlet.com/emilygilley/8mroyblhtzhp/wish/225223133 For my project I used pvc pipes, rubber bands, plastic spoon, screws, pvc glue and a hanger. We built the whole thing with pvc pipes and the spoon as the launching mechanism and used rubber bands for tension to help it go further. ]]> 2018-01-26 20:16:52 UTC https://padlet.com/emilygilley/8mroyblhtzhp/wish/225223133 emilygilley https://padlet.com/emilygilley/8mroyblhtzhp/wish/225223542 2018-01-26 20:18:25 UTC https://padlet.com/emilygilley/8mroyblhtzhp/wish/225223542 emilygilley https://padlet.com/emilygilley/8mroyblhtzhp/wish/225224886 2018-01-26 20:22:48 UTC https://padlet.com/emilygilley/8mroyblhtzhp/wish/225224886 emilygilley https://padlet.com/emilygilley/8mroyblhtzhp/wish/225225385 2018-01-26 20:24:28 UTC https://padlet.com/emilygilley/8mroyblhtzhp/wish/225225385 emilygilley https://padlet.com/emilygilley/8mroyblhtzhp/wish/225226614 This is supposed to be the blueprints alex cook is supposed t do this. I talked to you and you said not to do them.]]> 2018-01-26 20:28:30 UTC https://padlet.com/emilygilley/8mroyblhtzhp/wish/225226614 emilygilley https://padlet.com/emilygilley/8mroyblhtzhp/wish/225227141 This is supposed to be the calculations Fallon stayers is supposed to be doing this. I talked to you and you said not to worry about it.]]> 2018-01-26 20:30:12 UTC https://padlet.com/emilygilley/8mroyblhtzhp/wish/225227141 emilygilley https://padlet.com/emilygilley/8mroyblhtzhp/wish/225231597 I think that the testing and the launch went pretty well, we were ready to launch and it went pretty fast and it hit all the targets we didn't hit the 50 marks but we hit all the 40 marks. If I could do this again I would make sure that everything was even and strait and I would glue down pieces that were coming apart. If i glued it down then it wouldn't move a lot, because it was moving to much if i put too much tension on it.]]> 2018-01-26 20:47:09 UTC https://padlet.com/emilygilley/8mroyblhtzhp/wish/225231597
