Competition
We finally got to launch our trebuchet in the competition. For the distance we were to throw 25 feet for full credit but we only threw 22. Then we almost got full credit for the accuracy, but not quite. We named our trebuchet FAIL FTW, it means fail for the win because to be honest we didn't have very good confidence and our hopes weren't very high.

Project Plans
I havent completely decided what my overall plan is for this project. All I know is that I plan to built the base on wheels. If i do this correctly then it should aid in the distance competition because of creating momentum. But when it comes to the accuracy competition the I will probably use something to hold the wheels in place so that I dont exceed the target. But of course, if I do miss the target by throwing over it theni will allow the wheels to move.
Although I wanted to keep the project as midieval as possible and use the great Warwolf as my inspiration, I also am very competitive and want to win. So I plan to use ball bearings to reduce friction. But I havent decided whether I want to place them where the axel meets the the two support structures called trusses and glue the throwing arm to the axel so they all move as one, or I could place the bearings where the throwing arm meets the axel and glue the axel to the trusses. However I dont think i want to put ball bearings on both and let it swing freely.
In my last post I stated that I wanted to make a Floating Arm Trebuchet. I have decided not to go through with this idea due do time constraints.

Research
I've been researching the pros and cons of different types of trebuchets. I've also been considering making the Floating Arm Trebuuchet to maximize efficiency. But because of limited time on the actual building and testing of the project I will probably just make a normal Swinging Counterweight Trebuchet.
Floating Arm Swinging Couterweight
With this project, there will be two competitions. One will be a distance competition to where you must throw your projectile a set distance to get maximum credit. The second will be an an accuracy competition to where you must hit a make-shift wall hopefully knocking it down for extra credit.
With this, I plan to use multiple axel holes, one for maximum distance, and another that changes the trajectory therefore hopefully hiting the wall with enough force to knock it over.
