Week Four, Day One - Today, Alex went out to get our metal bar. This is what the arm of our Trebuchet would rest on, in order for it to function. Brandon and myself stayed back and worked on the arm of the Trebuchet as well as start working on the brackets, from the top of our arms, where we will have a pvc pipe acting as a pulley mechanism. 

Week Four, Day Two - Today we assembled all of the other things we needed for the Trebuchet to work. We braided our own rope in order for the entire thing to work. We also made a sling for the tennis ball to sit when we launch it. We also added our safety mechanism, which was a pin for the release. We also constructed our weight box, which is the key to to projectile motion. We put one weight consisting of 1000 grams. With this weight it launched exactly 10 yards. Then with two of those weights it launched 20 yards. Last, we added a one 12 inch, by 16 inch piece of wood right under the weight bucket. 

Week Four, Day Three - Today was the day, the moment of truth. Today we tested our initial question on whether or not we could be the dominant Trebuchet in our little war. The truth is we all failed. All of the trebuchets and catapults worked fine, it was just a matter of execution that every team lacked.

Week Four, Day Four - Today we started on our CAPA math assignments, as well as, finish any other pieces of the project we needed to do.
