In the joint notation scheme, which elements designate the joint types and what separator is used between assemblies?

• A. It uses color markers and a dash separator.
• B. It uses numerical codes with a slash separator.
• C. It uses joint symbols L, O, R, T, V and a colon to separate body-and-arm from wrist assemblies.
• D. It uses letters A through E with no separators.

Answer: (C)

In this notation, joint types are encoded with specific symbols (L, O, R, T, V) placed to indicate how adjacent segments move relative to each other. The colon serves as the separator between the main body-and-arm assembly and the wrist assembly, making it clear where one subassembly ends and the other begins. This combination—joint-type symbols plus a colon separation—gives a concise, unambiguous description of the arm’s joint configuration. Other schemes that use colors and dashes or numeric codes with slashes, or omit a separator, don’t match this established convention.
