Video Explanation about my Rude Goldberg system
One of the more challenging aspects of the Rube Goldberg system was the mechanical portion of the project. The building of the circuit was the easy part, for me. However, trying to figure out what pieces to use on the motor, the type of string, the diameter of wheels, etc. A lot of trial and error was used to figure out what I should use. I did you prior knowledge to infer on certain parts. I wasn't going to pick a really large wheel for example because their would be more friction.
The string that cranks the wagons in gave me a huge headache. It continuously got tangled and I tried using different string, different motors, different tensions. Finally I came to the conclusion of the correct string, with the correct motor speed and motor piece that winds the string.
