DESCRIPTION
TRANSCRIPT
Rube Goldberg Device
Team A1 - 4Hua Li, Ricky Whitener, Daniel Tobin
Things we considered◦Inefficient and Complicated◦Displays Banner for last step◦Able to be set off, and able to set off another
device◦At least 5 different Steps◦Budget limit ($20)
Device Design
Made of plywood blocksConnected parts with nails, screws, and
hot glueSteps triggered by balls setting off
mousetraps and weight releasing a clothespin
Overview of Structure
Summary of Operation
Conservation of Energy
ProjectileMotion
mgh = ½mv2
(y-y0)=(tanΘ)(x-x0)-(g/2v02)(1+tan2Θ)(x-x0)2
Rotational Kinetic Energy(uniform disc)
Elastic Potential Energy
KE = ½Iω2
I = ½mr2 Angular momentum
L = Iω
Ue = ½k(Δx)2
The project was confined to specific dimensions
Accuracy and reliability of materials
Availability of materialsParts going off accidentallyBuilding supports for parts
Issues
Teamwork makes work seem like funThere is physics behind all the motion in
the worldIn order to maintain simplicity, we made
some assumptions in calculations.Hot glue is key
Conclusions
