Wheel and Axle: The measuring wheel has a circular wheel with a circumference marked with units of length, such as feet or meters. The wheel is attached to an axle that allows it to rotate freely.
Handle: The measuring wheel typically has a handle that the user holds while operating the tool.
Counting Mechanism: As the user pushes or rolls the measuring wheel along the ground in a straight line, the wheel's rotation is translated into the counting mechanism. The counting mechanism records the number of wheel revolutions, and each revolution corresponds to a specific distance, which is usually marked on the wheel itself.
Measuring Distance: By counting the number of wheel revolutions, the user can determine the total distance covered by the measuring wheel. For example, if each wheel revolution corresponds to one meter, and the wheel completes 100 revolutions, the measured distance would be 100 meters.
