Backyard Ballistics

Applied Mechanics/ Structures & Mechanisms/ Manufacturing

Objectives/Goals Paintball guns have held my interest for a long time. Accuracy and distance are crucial ballistics questions in these games. This project investigated the effect of pressure…

CSEF · 2006

Bottle Rocket Blast-Off

Applied Mechanics/ Structures & Mechanisms/ Manufacturing

Objectives/Goals To demonstrate Newton#s third law of motion: That every action has an equal and opposite reaction. Pressurized water & air creates a non-polluting source of transportation b…

CSEF · 2006

Exploring Torque Using Pilot Holes in Wood

Applied Mechanics/ Structures & Mechanisms/ Manufacturing

Objectives/Goals This experiment tested how different size pilot holes affect torque required to advance screws into wood. The effect of screws versus bolts, and maple (hard wood) versus pin…

Fishing with the Pros

Applied Mechanics/ Structures & Mechanisms/ Manufacturing

Objectives/Goals The goal in my project is to find which, out of three poles will cast a weight the farthest. Methods/Materials We used: 1.Three fishing poles of different flexibillities; 2.…

CSEF · 2006

Gas Blast

Applied Mechanics/ Structures & Mechanisms/ Manufacturing

Objectives/Goals The problem seems to be that gas is very expensive, and Americans are having to get gasoline everyday. Could it be that Americans are driving to much or that the gas station…
