nearly finished

we have now nearly completed our trebuchet. last lesson we finished making the arm for the trebuchet and had to make a few adjustments to counter for the 4kg weight that must be used.

we then attached the arm to our trebuchet and did a few test runs with a light 1kg weight to make sure it works and it did! 



we should be finished our trebuchet next lesson. all we have to do now is make the wheels for the base to make it fly further and create a trigger mechanism to hold the arm in place when you go to release it.
