Protractor

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.

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.
