The Rube Goldberg Project
Process and Collaboration
• Originally, we had planned an elaborate series
of steps, which involved a bottle of wine,
several hammers and an acid/base powered
vehicle.
• We were then heartbroken to find that there
were limitations and dimensions to abide by,
so we scrapped our unnecessarily detailed
ideas...for other elaborate ideas.
The New Idea
• Our new idea involved a G.I. Joe bazooka, a
weighted-string-powered fan, Hot Wheels
tracks, and a zig-zag tier track.
Revamp
• After running a couple of mental test runs, we
decided that some of our original ideas were
neither reliable, nor feasible.
• The zig-zag track was too bulky.
• The bazooka was hard to trigger.
• There was not enough torque to turn the fan
at an efficient angular velocity.
Construction
• We found a small motor with a battery pack
and a hairpin switch perfect for our fan.
• The Hot Wheels track was replaced by tubing.
• A catapult was substituted for the bazooka.
• A funnel would be used in place of the zig-zag
track.
Re-revamp
• After assembling the Rube-goldberg, we found that
the fan was not powerful enough to blow the ball as
it was supposed to.
• We decided to drop the fan idea, and use the motor
as a wench.
• We also put another mousetrap at the beginning to
make it easier for the group before us.
• We also found another battery operated toy, the
Rammer Hammer, and decided to use it to trigger
the group after us/ electronic device.
Math
• Our Rube-Goldberg incorporates conservation
of linear momentum, conservation of
gravitational momentum, conservation of
angular momentum, translational energy,
collisions, angular velocity, angular
acceleration, liner velocity, liner acceleration,
mass moments of inertia, and rotational
translational energy.
