Today we got our 3d printed nose cones… Our groups was a fail. It was all my fault since I didn’t look at the measurements of the cone in the program. I am very guilty. The nosecone was supposed to be 3-2 inches.
Look at this monstrosity:
I learned that successful people fail a lot of times to get to the top. Now the measurements are okay and a classmate is printing it for me.
Today we learned to used tools to practice when we measure how far/high our rockets go. The tools that we used are called a Clinometer, for height, and a Trundle Wheel for length. The clinometer measures heights when you point it up and release the trigger, then the gravity pulls the arrow down, making the arrow point at the exact angle marked below. But it differs the angle on how far away from the thing you’re measuring. There’s an illusion, where when you back away from something, it seems to get smaller, then you point the tool lower, and it is not as high. For example, at 17 ft away from a flagpole, it is 40 degrees, but at 10 ft, it is 80 degrees.
The modern trundle wheel is pretty simple when you roll the circle at the end of the stick, it clicks every time you reach a meter. The old ones you have to look at the measurements on the face of the circle and stop every time you reach a meter.
