Hello! Can you provide response to each part of the problem by using physics concepts or formulas? Please also provide all math/formula/conceptual steps so that I can check my own work. This question may involve Moment of Inertia, Rotating Kinetic Energy, Uniform Circle, Torque, Parallel Axis Theorem, or other Physics concepts.

(Please no reposts!)

Physics Practice Problem Wind turbines Very large wind turbines have huge rotor blades that take a lot of energy to get moving. Sometimes they require a start-up motor to get moving up to speeds where they can generate their own power from the wind. In fact? wind turbines can draw excess power on the grid to store that energy as a ywheel. This wind turbine from Siemens, an automation company, has 3 rotors that sweep out a circle 113m in diameter. Each rotor (roughly half the diameter of the circle) weighs 67 metric tons. Estimate the moment of inertia as a uniform rod rotating about one enda very crude approximation that overestimates the moment (a) The minimum angular speed of the turbine is 6rpm. How fast are the tips of the rotors moving? (b) What is the rotational kinetic energy of the turbine at this speed? (c) Suppose you want to spin the rotors up in 2.0 hours. What constant torque do you need to apply to spin the turbine up to its minimum rotation speed of 6rpm? Assume no wind is blowing, so the only torque on the rotors is from the motor
