The Measurement of Period in a Windmill Blade Rotation
The Concept of Period in Windmill Blade Rotation
A windmill has three rotating blades. The tip of each blade traces a circle every 4 seconds. The quantity 4 seconds is a measurement of the period of the blade.
The period is the duration of time of one cycle. So if the tip of one blade of the windmill completes one circle around its axis of rotation, it means that it took the time of one period of 4 seconds to complete one cycle of rotation.
What is the meaning of the quantity 4 seconds in the context of a windmill blade rotation? The quantity 4 seconds represents the period of the blade, which is the duration of time for one complete cycle of rotation.
