  1. The GAMM 4.0 Gabrielle Sobel, Andrea Gingrich, Morgan McCann, & Marlene Woodings

  2. Design Overview • Step 1: Torque • Created from force of hand and radius of ruler • Step 2: Conservation of Translational Energy • Ball bearing rolls down pipe • Step 3: Projectile Motion • Ball bearing is shot into funnel • Step 4: Collision • Car and ball collide • Step 5: Mousetrap • Snaps and pulls cover sheet to display banner

  3. Calculation Overview • Torque was found by using • The Conservation of Translational Energy (assumed frictionless transition) was found with , , • Projectile/Freefall Motion was found using Conservation of Kinetic and Gravitational Energy equations: , , • Conservation of Momentum was found by solving simultaneous equations: , ,

  4. Technical Problems • Trouble machining because of small pieces • Unable to use clamps • Ball bearing placement in pipe • Sometimes shot out of funnel • Solved by moving ball further down pipe • Balancing pipe on pedestal • Used tension in rubber bands to allow pipe to pivot while secure • Excess friction between car and wood • Solved by placing scotch tape on wood

  5. Conclusions • Small design is more cost efficient • Device is compact and allows less room for error in calculations • Importance in communicating with peers
