Wind

What Are The Limitations Of The Model?
My model could hold three weights which is equil to 22.31 grams. When I added the fourth weight it couldnt quite spin all the way. The blades would slightly turn but could not completely go around. My model could also only spin with three weights if the fan was on high. Without that amount of wind my model failed to spin fluently.
How Do An Airplane And A Windmeal Use Air To Rotate?
They both have an air foil that creates pressure causing rotation within the blades.
Why Was It Necessary To Twist The Rodar Blades At An Angle?
Twisting the blades allowed it to have a resistance against the wind or the air flow. When there is resistance it helps the blades rotate with the wind direction.
