A Not So Bright Idea Kevin Black Matt Cowart Andre Wallace Daniel Wicker Bright Idea (Possibly)

Overview Water falls down a ramp and falls into pipe balanced at its center of mass which knocks a ball down another ramp. It then hits a cork acting as a pendulum which swings and hits another marble. That marble then rolls down a ramp and collides with the final marble which acts as a trap door making a lightbulb turn on.

Equations Used in Project Conservation of Energy mgh = 1/2mv^2 + 1/2I^2 Torque  = Frsin Center of Gravity R = (m1r1 + m2r2)/m1+m2 Angular Momentum Ib*b = Ib*b + Ic*c

Conclusions Each teammate showed up to every group meeting, supplied materials, and gave 1000%. We hope to “light up” the audience with our Rube Goldberg
