Design and Construction
A picture of us on our first meeting day ↑
Samples of all the needless equations we thought we had to solve
The schematic for an idea to use skateboard pieces in the catapult. We dropped this eventually.
Pencils and Play-doh that had to be sacrificed. For science. And idea communication.
Cutting up a hunk of thick PVC that would serve as the base.
Right at the last minute, Derek's father allowed us to use a hunk of what was formerly a door as a smooth base for the sling to slide on during launch.
Our sling, in the making.
The arm uses two pipes near the axle to ensure sufficient strength, which is important since it's PVC. Yeah, we have a lot of PVC.
Our weights are supposed to hang onto the catapult by hinge; that way, M1 can swing M2 a bit faster. Later, we made a hole through the top parts of that metal.
At first, Derek doubted Harry when Harry stated that using PVC would work. As we both later found out, it worked wonderfully.
This modification to M1 effectively makes our catapult's counterweight swing.
After attaching M1, the swinging arm, and the triangular support beams.
The end of L2 had been painted orange to ensure safety.
Okee dokee then! Looks like we're ready for our first test! (Derek is holding the camera, as in a lot of these photos.)
Our catapult prototype.
