The RG Stamper Team: Sean Meek Ryan Ray Mike Higgins Steven Stokes Introduction Stamp String and fasteners Two mousetraps Goal: Rube-Goldberg stamp device that uses projectile motion, conservation of energy and conservation of momentum Parts: Total cost: ~$13.75 particle board Sling shot Marbles Device Process 1 Sling Shot Uses elastic potential energy Converts to potential energy Launches ball into air 2 Funnel and tube Converts potential energy to kinetic energy Falls down tube 3 Collision and end of tube Conserves momentum Moves up 3.25 through tube Process (continued) 4 Mouse trap triggered Tension in string Pulls string through pulley system String pulls nail out 5 Stamper Elastic potential energy to kinetic energy Stored energy in mousetrap 6 Paper stamped Conclusion Goal reached All requirements met What we learned: Ways to adjust to group dynamics and schedules Opportunity to use concepts and theories learned in EF151
