Week 13: 5/17/2018

Image
Today we had to test both the trebuchet and catapult to see if they were capable of working and launching the ball far enough to get a decent grade. This went well and I think when we launch for a grade we will succeed. There may have to be some finishing touches on that day but overall it is looking good.

Today we finished the Trebuchet but need to add the sling for the final touch. We tested it and the weights did not cause the wood to split. This was good progress but now we have to create the sling to launch the object. Hopefully we can finish this Thursday but we have some people who are going to be absent for AP tests.


Week 12: 5/11/2018

Today we tested our Trebuchet arm. We gathered the weights and attached it to the arm using a thin metal rod. This allowed the weights to stay vertical throughout the process. When we tested it the rod that we installed went right through our wood because of the amount of force. This made us restart the whole arm and add extra support.

Today we further worked on the Trebuchet and it is not looking too bad. We added the support for the counter weights. Now we just have to get the weights and the rubber bands for the Catapult. We also continued to work on both of the instructables but we cant proceed onto the next steps if we are not finished with the constructions.

Week 11: 5/7/2018

Image
Today we finished the arm of the Trebuchet and continued to work on the instructables. This may take longer because we have found out that we need to do two instructables. One for the catapult and one for the Trebuchet. We need to acquire the source of power other known as the rubber bands. 






Week 11 5/3/2018

Image
We hope to finish the construction of the Trebuchet this week and get one test in. Its hard to find the right rubber bands for the Catapult, so we still need to order those which will complete it. We hope to find ones with enough strength to throw our ball 100 Yards without snapping our wood.










Week 10 4/23/2018

Today we worked on completing the Trebuchet and had decent progress with this task. The arm is a bit thin so we added support. We started to work on inscrutables but we ran into a problem because we did not take the necessary progress pictures needed in the instructable. We have to use the pictures that we have. We have also started to put the wheels on both the Trebuchet and Catapult.
