Mechanical Measuring Wheel
Once upon a time, in the golden age of invention, engineers and explorers sought the perfect tool—a device that could measure straight roads and the winding paths of undiscovered lands. Now, watch as the calibrated dials spin at different speeds, precisely capturing the length of any surface, whether a straight path or a twisting curve.
How to Use
The fully assembled curvimeter includes a measuring wheel, clock face, and hand. Place the device at the starting point and roll the wheel along to measure any curved or straight line. As the wheel turns, it moves the hand around the face, similar to a clock—but with markings indicating distance.
