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

Design 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: , ,

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

Technical Problems

Small design is more cost efficient Device is compact and allows less room for

error in calculations Importance in communicating with peers

Conclusions
