The Fighter with the Least Reflectivity

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…

The Physics of Roller Coasters

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…

What Affects the Speed of a Floating Object?

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…

Yo-Yo Physics

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…

Beware Ye Minifigures

Applied Mechanics & Structures

Objectives/Goals I wanted to find out how changes in projectile mass, counterweight mass, and throwing arm length affect the range and trajectory of a projectile launched by a trebuchet. Met…

Comparison of Fanwing Configuration Efficiency

Applied Mechanics & Structures Second Award

Objectives/Goals This project was made to find the relation between ducting on a fanwing propulsion system and its efficiency in thrust and lift. A fanwing works on Bernoulli#s principle & t…

Fun Factors

Applied Mechanics & Structures

Objectives/Goals My objective was to find the factor that most greatly decreases miles per gallon of the four I tested. Methods/Materials Method 1. Drive one car, with no applied factors, fr…
