3. Design Challenge: The wind turbine is designed to generate 2.5 MW of power with the blades rotating at 20 RPM. The large gear has 360 teeth and the small gear has 12 teeth. Design the high speed shaft to minimize weight. That is, choose a material (from your textbook) and cross-section dimensions such that the shaft won't yield, with a safety factor of 2.5, while keeping the shaft's weight to a minimum. Calculate the weight per meter of the shaft you designed. 2 Gear reducer High speed shaft Low speed shaft Generator
