Week Three, Day One  - Today we worked on the amr for our trebuchet. This is our recovery from a failure. Our first arm failed. We are redeisgning our arm to the dimenisons of the trebuchet. This will allow the arm to be fully recoiled and rotate before the weight hits the ground. We need our trebuchet arm to be under 60 inches when adding up all the arm lengths branching off from the main arm. 

Week Three, Day Two - Today we went out for our supplies. We pruchased 32 ft. of 2 by 4s for this project. After getting back to school, we started constructing our 48 by 18 base for the trebuchet.

Week Three, Day Three - Today we cut the arms to length and angles we needed, we then drilled the arms to the frame of the trebuchet. We did not drill the arms together though yet. We also, connect two 4 by 1 foot peices of wood under the base, to add extra support for our trebuchet.

Week Three, Day Four - Today we started construction on our arm for our trebuchet, as well as, finish drilling all the pieces of the trebuchet together. Today was when the whole thing really took it’s shape and we could see where we are going with the project.
