A motor-cycle engine crankshaft has an angular velocity of 523.6 rad/s and is in third gear of ratio 1.62:1. The final chain reduction is 4.7:1 and the effective wheel diameter 0.73 m. Calculate the road speed of the machine in km/h.

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

Hello, Could you please help with the question attached or give guidance please, thnk you

For the simple gear train shown, calculate the output angular velocity. 130 rpm Wout Output Input N = 20 N = 45 %3D Teeth N = 95
