A protractor is a geometric tool that is used to measure the degree of angles. A point where the baseline and a perpendicular line get intersected at the bottom of the protractor is called the origin of the protractor. Stock : – This is one of the contacting surfaces during the measurement of an angle. Hence, the origin of the protractor is also called by the following two other names. It is used for various objects like jigs.Sometimes the vernier scale in the bevel protractor has an attachment for giving a more precise reading. Parts of Vernier Bevel Protractor. Dial : – The dial is an integrated part of the stock. Bevel protractor has a very vital role in mechanical architectural drawing.

Also, we need to line up the ‘0’ angle on the protractor with the line we’re measuring the new angle from. Viewed 2k times 1. Try it below: It contains two circular scales in degrees and each scale is marked from zero degrees to one hundred eighty degrees semi-circularly. 4.8 out of 5 stars 45. From the supplier through to the technician and service advisor and on to the customer, all parties must be able to communicate freely and with minimal barriers while facilitating industry best practices that can be easily monitored by the operator. Most protractors are divided into 180 equal parts. This point is actually at middle of the protractor exactly. A bevel protractors come with a magnifying glass, which helps when reading angles more precisely. Different people use different terminology for expressing it but these three names are commonly used to represent the origin of a protractor. Bevel protractors are used to check angles on machines or parts with a high degree of accuracy. Baseline: The line along the bottom of the protractor is aligned along one of the angle's legs. FREE Shipping on orders over $25 shipped by Amazon. Protractor.NET is a unique, cloud based ALL-IN-ONE automotive shop management software program. It is used for a variety of mechanical and engineering related applications. This magnifying glass is used to see the value of the angles in the main scale and the vernier scale more clearly.Vernier Scale:The vernier scale is fixed on the swivel plate and it moves with the swivel plate. Main Scale. Add to Likebox #125327860 - Female doctor checking patients joint flexibility with goniometer. Radian-scale protractors measure angles in radians. At left side, the semicircular degree scale is denoted by the numbers from $0$ to $180$ in clockwise direction. The bevel protractor is used for testing the angles very precisely. protractor, compass, 2 set squares, ruler, sharpener, alphabetand number stencil pencil and eraser. expect statement will contain an actual value, and the second part of the expected statement should be the expected values.
