How is a handle bar a simple machine?

Answer 1

a simple machine, converts energy you have into a form you want. a handle bar converts a small force you put on the end bar into a larger torque that turns the shaft and the wheel into the pushing force you need to turn your bike.

Answer 2

A handlebar can be considered a simple machine because it allows the user to exert force at a distance from the pivot point (fulcrum), enabling a lever action to amplify the force applied when turning or steering. This leveraging effect helps in controlling the direction of movement with less effort.
