George Washington Gale Ferris. Jr., a civil engineering graduate from RPI, built the original Ferris wheel. The wheel carried 36 wooden cars, each holding up to 60 passengers, around a circle 76m in diameter. The cars were loaded 6 at a time, and once all 36 cars were full, the wheel made a complete rotation at constant angular speed in about 2 min. Estimate the amount of work that was required of the machinery to rotate the passengers alone.
I know the equations for Toque, and Work as well as force and Inertia, but if the velocity is constant, then isn't acceleration 0, which means no work is being done? It CANT be that easy. I am not sure how to start to solve. Any help is appreciated.
