When the edges of the beam and blade are parallel, a small mark on the swivel plate coincides with the zero line on the graduated dial.

Multiplying 3 by 5, the product, 15, is the number of minutes to be added to the whole number of degrees, thus indicating a setting of 28 degrees and 15 minutes.

Retrieved from ” https: We must measure the sample follows method to measure 3 times for each sample.


Demonstrate the proper method in using and taking care of the instrument. Universal bevel protractors are also used by toolmakers; as they measure angles by mechanical contact they are classed sxperiment mechanical protractors. Unfortunately, the two number scales on a one-sided protractor often confuse learners when first learning to measure and draw angles. Optical comparator have a good repeatability because the data from experiment recorded closed with the real value while the bevel vernier protector have a poor repeatability.

Most protractors are divided into equal parts. A bevel protractor is a graduated circular protractor with one pivoted arm; used for measuring or marking off angles.


Each angle is called degree. Zero on the vernier scale has moved 28 whole degrees to the right of the 0 on the main scale and the 3rd line on the vernier scale coincides with a line upon the main scale as indicated. Bevek instruments Mathematical tools Navigational equipment Technical drawing.

Unsourced material may be challenged and removed. This was a double sided protractor with one scale on each side, avoiding the confusion of having two scales together and enabling easier measuring and drawing of angles. The work piece was placed to the measuring equipment base part of bevel vernier protractor.


Multiplying 3 by 5, the product, 15, is the number of minutes to be added to the whole number of degrees, thus indicating a setting of 28 degrees and 15 minutes. Help Center Find new research papers in: Sometimes Vernier scales are attached to give more precise readings. Some expermient are simple half-discs. Picture below illustrates a variety of uses of the bevel bsvel. It has wide application in architectural and mechanical drawing, although its use is decreasing with the availability of experimebt drawing software or CAD.

August Learn how and when to remove this template message. Each space on the vernier scale is 5 minutes less than two spaces on the main scale. Last week, we did experiment about angle measurement. Since the spaces, both on the main scale and the Vernier scale, are numbered both to the right and to the left from zero, any angle can be measured.
