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 the distance 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 map that 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 in the scale.
You can rely on the curvimeter when planning a hike with your friends or
a family trip – it will help you to determine the distance you’d cover to get
to your destination. The device is especially useful when you have no access to
any electronic 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 its invention belongs to the Roman
engineer Virtuvius, who describes a very similar device around 23 BC. Others
refer to a Chinese scholar, Zhāng Héng. Russian sources suggest that the
curvimeter might have been invented by the polymath Mikhail Lomonosov who
presumably initially called it “krivimetr”. All in all, the official first
curvimeter patent belongs to the English engineer Edward Russell Morris who in
1873 registered “a novel device for measuring distances”.
Use
The Curvimeter is used to measure the length of curved lines on
topographic maps, charts, schemes, and plans. It is a common 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. The assembly of the model will be
interesting and won’t take much time.
