When laying out a radius on a corner, how is the center of the radius located?

  1. Using a compass

  2. Equidistant from the two adjacent sides

  3. At one corner of the workpiece

  4. By measuring with a caliper

The correct answer is: Equidistant from the two adjacent sides

The center of the radius is located equidistant from the two adjacent sides of the corner being rounded. This method ensures that the radius is consistent and symmetrical, creating a smooth curve that transitions evenly between the two sides. By determining the midpoint between the two adjacent lines or edges, you can establish the center point from which you will draw the arc of the desired radius. This technique is crucial for achieving accurate and aesthetically pleasing results in layout work, particularly in mechanical applications where precision is essential. Using this approach also allows for easier adjustments and ensures that the radius is adaptable to the specific requirements of the workpiece.
