Week 14 Thursday

Image
Today the rope ended up snapping and breaking on us as of right now the catapult is out of commission until we retrieve more rope. we added more wood support beams 4 X 4 across bottom of the cross bar and two 2 X 6 X 18 on the outside of catapult so that the wood did not snap on us again. i added eye hooks on back 2 X 6 board as our release mechanism. we also added three more 2 X 4 on top of post so the arm stopped earlier and launched the object in to the air. 

Week 14 Tuesday

On Friday of last week Joe came in after another AP test when he should have been in 3rd period. However 3rd period is a disappointing waste of a class so Joe had no problem with coming to engineering  instead. Joe was able to make a sling and he prepared the catapult for testing. The catapult performed very well. Even without maximum cranking of the handles the ball flew very far. Even though the project is considered late at this point we consider this a success due to this being the first functioning torsion catapult at South.


Week 13 Thursday

Joe has AP testing today so Jayce must work alone. Thankfully Jayce is an experienced craftsman so he was able to almost finish the catapult. 

week 13 Tuesday

Jayce bought the wood as well as eye hooks over the weekend. Today Jayce worked on replacing the broken wood while Joe wrote the instructable so that it is at the same step in the project as the actual catapult is. Jayce also used extra wood to double up the point at which the rope exits the base.
