2 10 Points In 10 Years Texas Tripled Its Wind Generating Capacity Such That Wind Power Now Is Cheaper Than Coal Here 1 (79.44 KiB) Viewed 34 times

2 10 points In 10 years, Texas tripled its wind generating capacity such that wind power now is cheaper than coal here. Consider a simplified model of a wind turbine as 3 equally spaced, 115 ft rods rotating about their ends. Calculate the moment of inertia of the blades if the turbine mass is 926 lbs: type your answer... Calculate the work done by the wind if goes from rest to 25 rpm: type your answer... If the blades were instead 30 m, calculate what the angular speed of the blades would be in rpm): type your answer... 3 10 points If the turbine of the previous problem were to become dislodged from the 100 m tower, and assuming the turbine ceases rotation before it hits the ground, calculate the speed of the turbine when it strikes the ground. (Note that the mechanics of this is more complicated due to the geometry of the turbine, a blade could strike at the tip, or two tips could strike together. Ignore all this.) type your answer...
