Applied Mechanics & Structures
Objectives/Goals It is believed that fighter shape reduces its appearence to radar. An F-22 Raptor will be the least detectable because of all of it's sharp edges. Methods/Materials # 32#x25…
CSEF · 2010
Applied Mechanics & Structures
Objectives/Goals The experiment was conducted in order to test the effect of the speed of a rotating flywheel within a vehicle on the momentum and stability of a turning vehicle. It was hypo…

Applied Mechanics & Structures
Objectives/Goals The purpose of this study was to investigate the effect of golf ball temperature on the distance that the ball would travel upon impact. We predicted that when the golf ball…
CSEF · 2010
Applied Mechanics & Structures
Objectives/Goals My favorite subject being math, I wanted to do something that included many formulas and calculations. I decided to design an experiment in which I could learn more about ho…
CSEF · 2010
Applied Mechanics & Structures
Objectives/Goals To determine manufacturing factors such as material characteristic of paintball, design of barrels and design of air tanks on whether the paintball will hit or miss. We will…
CSEF · 2010
Applied Mechanics & Structures
Objectives/Goals Objective: The most of wind turbine generator in California have two blades. So I made an experiment to build a wind turbine with an optimal number of blades that is best su…
CSEF · 2010
Applied Mechanics & Structures
Objectives/Goals The purpose of our experiment was to test for the cleanest running jet fuels from a choice of propane and Av-gas, and compare them to the most commonly used jet fuel, Jet-A.…
CSEF · 2010
Applied Mechanics & Structures
Objectives/Goals Hypothesis: The more massive the counterweight, the further the projectile travels. The more potential energy stored in the counterweight, the more kinetic energy the projec…
CSEF · 2010
Applied Mechanics & Structures
Objectives/Goals I mainly want to find out if the floating speed of an object depend only on the object volume or also on some other factors when the object is floating across a certain dept…
CSEF · 2010
Applied Mechanics & Structures
Objectives/Goals The goal of this experiment was to see if expensive fingerboard wheels go farther and create less friction than less expensive wheels. Methods/Materials Four wheels were tes…
CSEF · 2010
Applied Mechanics & Structures
Objectives/Goals The purpose of this project was to construct bridges of three different designs (span, truss, and modified arch) to determine which would be more structurally sound when wei…
CSEF · 2010
Applied Mechanics & Structures
Objectives/Goals The purpose of this project was to find out which type of bridge is the strongest - arch, beam, or truss. My hypothesis was that the arch bridge would be the strongest. Meth…
CSEF · 2010
Applied Mechanics & Structures
Objectives/Goals Determine what effect (if any) the weight and string length of a yo-yo have on its "sleep time," which is the time it stays at the bottom of the string when the yo-yo is thr…
