The problems and challenges The challenge is try to help our planet and environment from pollution. Since our planet has to much pollution wind turbines are an easy way to help reduce this. The problems and challenges

The constraints with turbines are that they are expensive and hard to build. Another constraint would include actual wind because if you don’t have wind the turbine would not make any energy. Constraints

Research We did some research on how pollution affects us and our environment. Our goal for our research was to develop a turbine with non expensive or recycled materials. That spins/rotates fast in order to make energy.

REFLECTION #1 UPLOAD VIDEO How did your team’s first blade design work? Was your team successful in building your base/stance? Why? What are some of your team’s improvements for your second design?

REFLECTION #2 UPLOAD VIDEO How did your team’s second blade design work? What is your team’s ideas for blade materials to use for your third blade design? Why is your teaming using this particular design for your base/stance?

the gear ratio is 32 :1 the top is 64 to 16 and the bottom is 64 to 8 or 4:1, 8:14. 4 times 8 is 32 so it’s a 32:1 gear ratio our pitch angle is about 15 we tried many angles including 30 ,25 even 5 but we figured that 15 was a really good angle. direct current is like a flash light it goes directly where u point it alternating current flickers and also moves up and down. this is our nesel is the that holds and keeps everything together. all generator are ac current Reasonings
