Define a problem
Purpose:
The purpose it to slowly carry the marble down to the cup, to be as inefficient as possible essientally. It starts at 12 inches high and slowly carries down to the cup on the ground.

Brainstorming:
-incline plane
-gears and sprockets
-levers
-pulleys
We were thinking about using a lever to control the gears which were connected to a pulley system that would let a rope down on an incline plane.

Explanation:
The experience was strange to say the least, I think I definitely overthought it at first but with the collaboration of my teammates we were able to figure out solutions to multiple problems. Dealing with multiple simple machines at first was nerve wrecking but after we finished, it was very nice to see the product of our ideas come together. The testing result was definitely frustrating, we constantly were worried about calculating the wrong thing since we were calculating multiple machines and one mistake could screw us up. Not to mention the constant need for editing the machines to adhere to our constraints and goals. We definitely learned that it was okay to disagree and give our own ideas, also how different machines worked together, and that you do not always have the best idea and that s okay. I learned it when I proposed multiple incline planes along with pulleys but struggled to explain the logistics. My team followed me but quickly realized it was not really thought-out and we needed to try a different route, so we talked and someone brought up an idea of a type of reverse elevator with incline planes. We constantly had to adjust the height of the incline plane as the square that carried the marble kept getting stuck with the holes of the beams that we could not change. Our simple machines were thought up rather quickly as we made many mistakes, but the experience was awesome and there were definitely a lot to take away from.

1st Picture: We were setting up the bases for our machines, we were figuring out where to put our gear and pulleys.
2nd Picture: We decided a placement for our incline plane, and we were trying to align it with our gear and belts.
3rd Picture: We finished with the incline plane connected to our gears and pulley which is controlled by a lever.

conclusion
Reflection:
- The easiest mechanism to determine the drive ratio would be the sprockets as we had to input a simple formula and simply divide. It was a basic two step problem.
- The hardest mechanism to determine would be the pulley as we had to implement multiple steps for our calculations. It takes a lot of steps and additional math to calculate.
