What is the level of accuracy for a universal bevel protractor?

  1. 1 degree

  2. 5 minutes of a degree

  3. 10 minutes of a degree

  4. 15 minutes of a degree

The correct answer is: 5 minutes of a degree

A universal bevel protractor is designed to measure angles with a high level of precision, typically allowing users to make accurate measurements up to 5 minutes of a degree. This is significant because it gives the user the ability to assess angles much more finely than just a single degree, which is crucial in many precision machining and alignment tasks. Understanding the level of accuracy is essential for applications requiring careful alignment and fitting of components, where even minute discrepancies can lead to improper functioning or increased wear. The ability to measure to 5 minutes of a degree provides the necessary detail to ensure high-quality outcomes in the work performed.
