Windmills

1. Which roder had the most power and why?- The purple roder with four sides had the most power because it had more room for the wind to hit it and push it. 2. What was different about the design that had the most output?- it was shorter but wide on the inside. It had more space for the wind to go in and push it. 3. What are the limitations or model?- the model is roud and deep inside. Some limitations of our windmill are we could made the windmill longer instead of it being short. 4. How does an airplain and a windmill use pressure to fly?- a windmill has a smooth but roudish figure when the wind hits the widmill the wind will go smoothly over the mill and get caught in the curves which pushes it around. 5. Why is it necessary to twist the roder blades at an angle?- so the wind can fly smoothly over and around the windmill while still pushing the windmill. 6. Explain how roders of a windmill and the sail of a sailboat have the same principle.- They bothe are tilted to catch the wind to make the objects move. Power of our windmill- 6.5 High Energy- 69.96 Mass- 7.5 Time- 41 sec.
