Dec. 12Team Whitey3 Introduction e Create P.F.A.D.S. e Compete against other P.F.A.D.S. e Must follow given constraints

Dec. 12Team Whitey4 Constraints 4 18x 18x 18 4 No more than 10 pounds 4 Less than $20

Dec. 12Team Whitey5 Criteria 4 Minimize weight 4 Maximize accuracy 4 Minimize volume 4 Rolls/slides straight

Dec. 12Team Whitey6 Objectives 4 Practice the design process 4 Learn about projectile motion 4 Work as a team

Dec. 12Team Whitey7 Preliminary Ideas 4 Rubber Band 4 Flexible Steel 4 Mousetrap

Dec. 12Team Whitey8 Rubber Band

Dec. 12Team Whitey9 Flexible Steel

Dec. 12Team Whitey10 Mousetrap

Dec. 12Team Whitey11 Refinement 4 Flexible steel not accurate 4 Rubber band not powerful 4 Mousetrap idea best fit 4 Spring loaded catapult

Dec. 12Team Whitey12 Spring Design

Dec. 12Team Whitey13 Implementation 4 Decided on mousetrap 4 Mousetrap failed, changed to springs for more power.

Dec. 12Team Whitey14 Final Design

Dec. 12Team Whitey15 Construction 4 Listed parts needed and bought them. 4 Used Tool from Tobys Room 4 Made working design

Dec. 12Team Whitey16 Testing 4 Mousetrap idea was too weak 4 Went back to decision process 4 Decided on a stronger spring design

Dec. 12Team Whitey17 Final Mechanism 4 Slides on boards 4 Spring powered 4 Pulley triggered 4 Weight

Dec. 12Team Whitey18 Picture Of Final Design

Dec. 12Team Whitey19 Results 4 Trigger Mechanism did not work in competition. 4 Resulted in embarrassment and no score. 4 Advantages 4 Disadvantages

Dec. 12Team Whitey20 Recommendations 4 Mousetrap is not powerful enough 4 Wood and metal 4 Add better mechanism for rolling straight.

Dec. 12Team Whitey21 Conclusions 4 Need a better design 4 Needed more testing before competition. 4 Needed more reliable materials.
