Our Machine Runs by use putting a marble behind a board in a hole that then sends it down a screw. It then falls into a inclined plane. from there falls in a hole with a cup that has a pulley attached to it. It lifts a wedge that allows a car to roll down another inclined plane. It hits a tennis ball that falls into a cup attached to a lever/ That lever is connected to pulleys that controls another lever. Once the force is applied to that next lever it sends marbles down a tube to hit another car that has a stylus attached to it. It rolls down a small inclined plane and the tip of the stylus hits a small ipad button to take a picture. All of our calculations are i the google document below.
All of our Calculations are in the Google slide above
Concepts:
Mechanical Advantage- Is a measure of the force amplification achieved by using a tool, mechanical device or machine system.
Force- Is any interaction that, when unopposed, will change the motion of an object.
Kinetic Energy- Of an object is the energy that it possesses due to its motion
Potential Energy- Is the energy that an object has due to its position in a force field or that a system has due to the configuration of its parts.
Work- When acting on a body, there is a displacement of the point of application in the direction of the force.
Velocity- Is a vector quantity that refers to "the rate at which an object changes its position."
Energy Transfers- Energy cannot be created or destroyed, only converted from one form to another.
Impulse- Is a driving motivation or force

Construction Log:
Day 1: Joey, Josh, and I started by getting our two 2in by 4in pieces of wood in an upright shape so it had a bottom and a side to start everything.
Day 2: We started to finished our schematic and got the materials needed for the first step.
Day 3: We started to build that pipe and halfway through Joey realized that this wouldn't work. So I came up with the idea to drill a hole and go from behind.
Day 4: We built the two ramps and drilled the hole for the pipe to run through and we tested it.
Day 5; We realized we didn't have enough steps for our project, So Joey thought of the pulley system attached to the wedge. And we got the ledge for the tennis ball set up.
Day 5 and 6: Here we ran into some problems because we didn't know how to set up the lever system and we ran out of height and room. So we used a nait and a screw for the lever and to solve our height problem we attached to pulleys
Day 7: We made agreements bring the required materials for our project.
Day 8/Weekend: we made our blueprints for the next steps that we needed to finish and we got the materials
Day 10 and 11: We finshed our project and tested to see if it works. We also started our second bluprint and our calculations while started our google slide.
Day 12: We finalized our project and finished our calculations and schematic . We just had to add some finishing touches to our google slide.

Some problems we came across was that we ran out of room. And we ran out of height.
Reflection
Our group consisted of Me Josh Jossart And Joey Stickle. So I learned a lot of things from this project and I thought it was a great way for us to start this year as freshman. One thing our group could have done as a whole was not make fun of others ideas, or just take into consideration what they are saying. Another thing is be more on task. I could have helped by keeping them in check, but I sometimes daydreamed myself. I learned that big projects shouldn't be procrastinated and left till the last minute. Because honestly it didn't work until like three days before presentation night. And we started late on the calculations so we were behind all the other groups. But we devoted our lunches to gt it done and we did.. I also learned that I should be more confident in my ideas and be more of a leader. I had a blast doing this project and I am excited to see what else STEM holds on the table.
