Our trebuchet was very successful in the accuracy part of the challenge project with our closest throw to be within one meter of the center of the hula hoop. This earned us second place in the challenge! From that we scored 9/10 points in the accuracy part of the competition.
I would have improved our trebuchet by coming up with a more consistant way to make it accurate to 15m. I would have rather taken off the counterweights instead of added bungee cords because I feel it would more accurately place each throw at 15m. Even on competition day we had a few test trials that made us realize that we needed to alter the bungee cords. They were not the greatest choice because if they were slightly altered the whole overall performance of the trebuchet was compromised and that could have happened very easily, we were lucky that it didn't.
If I were going to build a brand new trebuchet there are not many things that I would change except for possibly raising the height that the counterweight had to fall and increasing the mass of the counterweight which would have increased the range. As well what I posted above I would do to alter the accuracy part of the competition.
