Rube Goldberg Machine
Design Brief
Client Company:
Jimmy clowns
Designers:
Jackson and Ethan
Problem Statement:
Jimmy clowns has experienced increased demand at parties and do not have time to pop balloons so they need something that can do it for them
Design Statement:
We will build a compound machine that will contribute to other machines that will pop a balloon, we will build this machine with vex and recycled parts and test it
Design Criteria:
Must be built out of vex materials and recycled parts. Must pop a balloon and have at least three simple machines with a mechanical advantage of 1 or greater
Design Constraints:
Only use vex and recycled parts, 4 days to work, mechanical advantage greater than one, work with other groups

Conclusion Questions
1) For which mechanism was it the easiest to determine the mechanical advantage or drive ratio? Why was it the easiest? It was easiest to find the mechanical advantage for the inclined planes because all you had to do was measure it and do a simple division problem.
2) For which mechanism was it the most difficult to determine the mechanical advantage or drive ratio? Why was it the most difficult? The lever was the most difficult because the Fr was hard to find because it was gravity.
3)What modifications could you make to your compound machine to make it more mechanically efficient? It already is efficient with an overall mechanical advantage of 1,040:1.
