When laying out angles with a bevel protractor, what is the accuracy attainable?

+/- 1 degree
+/- 0.5 degrees (30 mins)
+/- 2 degrees
+/- 15 minutes

The correct answer is: +/- 0.5 degrees (30 mins)

A bevel protractor is a precision tool used to measure and lay out angles in various machining and assembly tasks. The accuracy of a bevel protractor is typically around +/- 0.5 degrees, which is equivalent to 30 minutes (30 mins), meaning it can measure angles with a high degree of precision. When using a bevel protractor, the user can read the scale directly, allowing for fine adjustments, and the design of the tool aids in achieving a reliable measurement by having a clear reference line. This capability makes a bevel protractor particularly valuable for machinists and millwrights who require accuracy in dimensions and angles for their work. In contrast, other choices suggest lower or significantly less precise accuracies, which do not reflect the practical performance of a bevel protractor. Therefore, the choice indicating +/- 0.5 degrees is grounded in the standard operational specifications for such tools.
