This week I made a automata cam. Since this was my first time my arm the went up and down got stuck at some times. I might have glued it by accident. Next time I should probably be more careful with the glue. Also, I used a slice cutter to cut the paper. A slice cutter is very helpful when you are cutting inside the shape itself.

This week I made a catapult. I had to find the MA, effort arm, and load arm. I made my catapult into a game. The catapult was simple but still worked really well.

This week I made a truss out of carrots and toothpicks. Mine held 5 books. I think the carrots hated me because they wouldn’t balance correctly. The problem was the uneven carrots because they didn’t holdup the books to well. Next time I should probably make the carrots even so that the sides are flat.

After I saw the video for the I-beam I started to see them EVERYWHERE. My I-Beam held 10 cans of food, but my own design only held 1. My own design was very floppy which is probably why it only held one can of food. I thought the sides would  help, but I don’t think they did.

I did not know that for glue there was a set time, a cure time, etc. I just through that if you put glue and let it sit your good. Also knowing the techniques for gluing was very useful.
