A Ferris wheel is an example of what kind of simple machine?
Answer Wheel and axle
More than 100,000 parts went into the first Ferris wheel in 1893, notably an 89,320 pound axle that had to be hoisted onto two towers 140 feet in the air. Over the next 19 weeks, more than 1.4 million people paid 50 cents for a 20 minute ride.
