5 mm is the least count of theodolite.
least count of theodolite is 1 second
0.03mm is the least count for feeler gauge
Bevel gears can be used to change the direction of drive in a gear system by 90 degrees
the one that had smaller least count wil be more accurate
The least count of a vernier bevel protractor is typically 5 minutes or 0.083 degrees. This means it can measure angles with an accuracy of 5 minutes or 0.083 degrees.
universal bevel protactor is an angle measuring instrument which measures acute angle ,obtuse angle as well as it is used to layout an angle. its least count is 5 minute.
The least count of a bevel protractor is typically 5 minutes, which means it can measure angles to the nearest 5 minutes or 1/12 of a degree.
it's used to take angle measurement
Protractor or bevel gauge.
There's the protractor, a bevel gauge, and the plain ol' measuring tape with pen and paper.Inclinometer.
The bevel protractor is commonly used by woodworkers whoneed to make a more complex design with angles other than 45 and 90 degrees. Most circular table sawsprovide a scale for cutting the correct angles. However, like a basicprotractor, the scale is not as small and exact; the lines are oftenthick and difficult to match up with the wood. In order to achieve thebest results, marks can be made directly onto your building materialsusing a bevel protractor, and then the saw can be used to cut alongthe lines you have created. For large projects like building treehousesand playgrounds, a bevel protractor is a wise investment. It willassist in every stage of the buliding process from drafting to puttingon the final touches. In no time at all you will be able to design andconstruct a unique place for your children to play, that is also safe.
you will go to north protractor it means 0 and count up to the line of the angle example:
When inserting a needle, the needle is inserted bevel up.However, at least 1 study suggests (in the same article) that bevel down may help on difficult sticks, on pediatric or dehydrated adults.
