What are the two types of dividers?

• A. Firm Joint and Spring Type
• B. Fixed Joint and Adjustable Type
• C. Spring Type and Sliding Type
• D. Large and Small Type

Answer: (A)

Dividers are commonly classified by how the two legs are held apart and kept at a set width. The two main styles you’ll encounter are firm-joint dividers and spring-type dividers.

A firm-joint divider clamps the distance with a screw or bolt, so once you set the width and tighten it, the legs stay locked in place. This gives high precision and stability, which is preferred when you need repeated, consistent transfers of measurement.

A spring-type divider uses a small spring to exert tension between the legs. This makes it quick and easy to adjust the width because the spring provides constant, light resistance without needing to tighten a screw. It’s handy for faster, less rigid work where you’re changing measurements frequently.

The other descriptors don’t reflect these common categories, which is why the pair firm-joint and spring-type is the best fit.
