Which of the following statement is correct about the adjustable blade?Ī) The adjustable blade has an attachment with the main body.ī) The adjustable blade is capable of rotating freely about the centre.Ĭ) The adjustable blade is capable of rotating freely about the free edge.ĭ) The adjustable blade is having an attachment with a base plate.Īns. For example, the zero that is on the vernier scale lines up with the mark of 85 degrees. Read the number of the degrees present on the main scale, directly above the zero present on the vernier scale.The vernier scale is smaller on the inner side of the protractor. Align the base of the protractor on one side of an angle, and then swivel the blade for making the other side of the angle.It loosens the blade so that we can swivel it. Firstly, unscrew the large clamp on the front part of the protractor.However, as the dial is graduated from opposite 0 marks to 90 degrees each way. The reading might come from the graduation number on the dial indicated by the mark present on the swivel plate.įor measuring an angle of over 90 degrees, we have to subtract the number of the degrees as indicated on the dial from 180 degrees. To measure an angle between the beam and the blade having an angle of 90 degrees or less. When the edges of the beam and the blade are parallel, a small mark on the swivel plate coincides with the 0 lines on the graduated dial. The bevel protractors have a beam, a graduated dial and a blade that has a connection with a swivel plate (with the vernier scale) by the thumb nut and the clamp. It reads to 5 arcminutes and can also measure angles from 0 degrees to 360 degrees. The bevel protractor is useful for establishing and testing the angles to very close tolerances. It plays a very important role in the mechanical and architectural drawing, although its general use is decreasing with the availability of the modern drawing software or CAD. Sometimes the vernier scales have an attachment for giving more precise readings. ![]() What is Bevel Protractor and Bevel Protractor Range?Ī bevel protractor is an instrument that is graduated spherical protractor with one pivoted arm that we use for making off the angles. Its most common use is in the schools for the students, we all know this, using it in the geometry classes in the mathematics class is very common and usual. We use them for a variety of mechanical and engineering-related applications. Many precision protractors further divide the degrees into the arcminutes. The radian-scale protractors measure the angles in the radians. Mainly the protractors measure the angles in degrees. It is typically made up of transparent plastic or maybe glass, for doing a measurement of angles. Various bevel protractors will have a vernier scale on them that normally exists underneath the degree scale.Ī protractor is an instrument we use for measuring. Its base is present on the bottom side of the angle, whereas the blade moves to match the opposing side. ![]() Unlike a normal protractor, we adjust a bevel protractor for fitting an angle. Whereas, this occurs when we produce engineering/machine drawings. We see people using it with various objects that include jigs. 1.4 Solved Question for You Introduction to Bevel Protractorīevel protractor is an instrument that we use for measuring the angles of the objects. ![]()
