Windmill Results

Mass    Height   Energy   Power   Time
7.83g   .7874m  60.54j     1.06w    20s
14.7g   .884m    128.85j   7.336w  20s

  • Which rotor has the most power? Why? The second one because it was wasn't too light and wasn't too heavy.
  • What was the different  from the design with the most output? It had longer wings.
  • What are the limitations to the model? We could've made it bigger and maybe try to get more weights to be lifted.
  • How do airplanes and windmills compare? They use their wings to move.
  • Why did we twist the rotor blades at an angel to grab the wind? So that it would spin easier and faster.
  • Explain how windmills and sailboats use the sane principles. When the wind hits from a distance it seems to move faster, you don't want to be right up close to the windmills and sailboats because it will slow it down or won't even move at all.
