Find out about the Curvimeter's design and how it works

The Curvimeter - or opisometer - is a device that measures the length of curved lines and helps to calculate thedistance between the points on a map more precisely than a ruler or a compass.

The mechanism has a measuring wheel, a clock face and a hand. When the wheel moves along the line on a mapthat you need to measure, the hand moves around the clock face marked with measuring units - centimeters,inches, etc. All you need to do in the end is to check the map scale and to multiply your data by the denominator inthe scale.

You can rely on the curvimeter when planning a hike with your friends or a family trip - it will help you to determinethe distance you’d cover to get to your destination. The device is especially useful when you have no access to anyelectronic gadgets or the internet.

Who invented the curvimeter and when

There is no verified information about the actual inventor of the curvimeter. Some sources say the credit of itsinvention belongs to the Roman engineer Virtuvius, who describes a very similar device around 23 BC. Others referto a Chinese scholar, Zh?ng Héng. Russian sources suggest that the curvimeter might have been invented by thepolymath Mikhail Lomonosov who presumably initially called it "krivimetr". All in all, the official first curvimeterpatent belongs to the English engineer Edward Russell Morris who in 1873 registered “a novel device for measuringdistances".

Use

The Curvimeter is used to measure the length of curved lines on topographic maps, charts, schemes, and plans. It is acommon tool for map-makers, tourists, and road services.

The Mechanism of the curvimeter is made of:

  • Measuring wheel with main and additional scales, and a hand.
  • Planetary mechanism.
  • Cycloidal drive.

Ugears STEM-models are designed to suit different age groups with a special focus on learning component. Theassembly of the model will be interesting and won't take much time.
