1. Engineering Hangover Members Joel Bonds Christopher Cox Jeffrey Hall Jonathan Rhyne Engineering 151 Final Team Project

2. Engineering 151 Final Team Project: Engineering HangoverJ. Bonds, C. Cox, J. Hall, J. Rhyne • Device Overview and Purpose • Components • Newton’s Cradle • Foosball • Wooden Ramp • Dominos • Alka-Seltzer • Cup • H20 • Tape • Purpose • Drop two Alka-Seltzer into a cup to alleviate a hangover.

3. Engineering 151 Final Team Project: Engineering HangoverJ. Bonds, C. Cox, J. Hall, J. Rhyne • Design and Construction Issues • Finding accurate heights to make all collisions work correctly. • Calculating final domino position to knock Alka-Seltzers into the cup. • Making ball sit at top of ramp until initial collision. • Laziness. • Time (working out meetings and schedule conflicts).

4. Engineering 151 Final Team Project: Engineering HangoverJ. Bonds, C. Cox, J. Hall, J. Rhyne • Energy Conversions • Newton’s Cradle – Potential to Kinetic back into Potential • Collision/Conservation of Momentum • Ball – Potential into Kinetic • Collision/Conservation of Momentum • Dominos – Potential into Kinetic • Collision/Conservation of Momentum • Alka-Seltzer – Potential into Kinetic into Chemical • Collision/Conservation of Momentum/Chemical Reaction

5. Engineering 151 Final Team Project: Engineering HangoverJ. Bonds, C. Cox, J. Hall, J. Rhyne • Conclusions • It would be more efficient to just drop a few Alka-Seltzer into a cup. • We strictly adhered to the guideline that “it is better to have a simpler device that works rather than a complex device that doesn’t.” • Making a Rube-Goldberg machine is fairly simple, and yet highly inefficient to perform a simple task. • It is simply a sequence of reactions and learning the correct spacing to make everything work together. • We realize that by definition our machine is inefficient, yet for the purposes of our calculations we have assumed perfectly elastic collisions.
