RUBE GOLDBERG Allen Huang Peter Laciano Kevin Shi T-Pak Attack

Project Goals Use creativity and available materials to design a contraption. Base principles on Rube Goldberg designs and series of causes and effects. Understand the laws of physics surrounding the resulting actions of our machine. Score an epically awesome goal in Foosball!

Project Goals Sequence of the Final Set-Up Vibrating phone  slide down incline  knock K’Nex spinner  spinner/domino sequence  knock dominoes up incline  knock marble down books  hit golf ball down ramp into support  cup lowered and golf ball released down ramp  ball hits yo-yo  yo-yo drops into cup starting lever sequence  ramp lowered by string 

Project Goals Sequence of the Final Set-Up (cont.)  golf ball rolls off incline onto Go board  ball hits sequence of books  last book falls pulling down attached basketball  weight of basketball pulls handle on Foosball table  Foosball player spins and hits ball into goal

Results and What was Learned Results: Overcame difficulties –Setting up long, complex sequences of dominoes –Releasing ball from cup –Devising mechanism to drop basketball off table –Getting Kevin Shi’s phone to send message Accomplished goal Learned: Precision in cause and effects –Orientation –Distance –Force Reality of simple machine creation –Level of complication –Availability of materials

Physics Principles Law of Conservation of Energy - energy cannot be created or destroyed; only changes forms Rotation - moment of inertia; torque; e.g. k’nex spinners Projectiles - vectors; e.g. yo-yo Incline Plane - parallel/perpendicular force; friction; e.g. golf ball down ramp Center of Mass - velocity center of mass; collisions; e.g. dominoes hitting marble

Areas for Additional Study *Have covered general principles of all parts of our Rube Goldberg machine * vibrations; tremors (vibrating cell phone) structures; buildings (ascending ramp for dominoes) radio waves (initial cell phone text message)

Conclusion Ball always traveled down incline and hit yo-yo Yo-yo consistently landed in bucket Golf ball always rolled down incline and knocked down books Marble rolled down book incline and hit golf ball Lever system consistently pulled down incline w/ golf ball Intricate domino design was time- consuming and delicate Sword could possibly fall down from vibrations of dominoes hitting the table Sliding cell phone could possibly fail to trigger K’Nex singer/domino sequence Basketball could fail to be pulled down by book WorkedDidn’t Work Project was frustrating, time-consuming, and mentally challenging, yet educational and rewarding to complete Overall
