  6. Demonstration

  7. Demonstration

  8. In Use

  9. Feasibility: Beyond Foam • Energy Conservation • Spring PE = Golf Ball KE • kθ2 = mv2 • For 200 yd Launch: • Torsion Springs w/ k = 35.3 N-m • Special order…but feasible

  10. Take-A-Ways • Spring needs custom manufacturing • Destroyed Springs

  11. Take-A-Ways • Release Mechanism needs force to keep pin in place • Rubber Bands

  12. Future Consideration • Structurally Stable • Trajectory/Distance adjustments • Load Ball Automatically • Alternative Launching Mechanisms
