What tool is used for scribing a circle that is beyond the range of the dividers?

  1. Caliper

  2. Trammels

  3. Vernier gauge

  4. Surface plate

The correct answer is: Trammels

The tool specifically designed for scribing larger circles beyond the range of dividers is the trammels. Trammels consist of a beam or rod that can hold one or two adjustable points or scribing tools at either end. This design allows users to effectively scribe large circles or arcs by pivoting the beam around a centered point, facilitating precise measurements over greater distances than traditional dividers can handle. Calipers, while useful for measuring distances and dimensions, do not offer the same capacity for marking large, precise circles. A Vernier gauge is primarily used for measuring linear dimensions with high accuracy but is not meant for scribing. Similarly, a surface plate is an essential tool for providing a flat reference surface for setups and inspections, rather than for marking or scribing circles. Therefore, trammels are the most appropriate tool for this particular task.
