Compound Machine Design
The task for this project is to create a compound machine that can lift a weight of 8 ounces up 6 inches. However, the criteria for this problem are:
- It must use at least 2 simple machines, and at least one gear system, chain and sprocket system, or pulley and belt system.
- Also, each mechanism must have a mechanical advantage greater than 1, and the overall system must also have a mechanical advantage greater than 1.

We made in total about 5 minor modifications to the machine that weren’t in the final sketch.
In the final presentation, our machine functioned just as we expected. Previously, we had some slight issues with the balance, but it went without a hitch. It was well under the 3 minute time limit and lifted around 3 inches. Sprocket A is the one at the top left, with the crank on it, which leads to sprocket B, the small one, on the same shaft as C, which leads to D, which is the wheel and axle for the spool with the thread for the block and tackle. |
