[#125] In a kinematic chain, a quaternary joint is equivalent to
Correct Answer
(C) Three binary joints
Explanation
Solution: In a kinematic chain, a quaternary joint is equivalent to Option A: One binary joint This option is not correct . A quaternary joint is not equivalent to just one binary joint. Option B: Two binary joints This option is not correct . A quaternary joint is not equivalent to two binary joints. Option C: Three binary joints This is the correct answer . In a kinematic chain, a quaternary joint is equivalent to three binary joints. It means that the motion and constraints at a quaternary joint can be represented by three separate binary joints. Option D: Four binary joints This option is not correct . A quaternary joint is not equivalent to four binary joints. Therefore, the correct answer is Option C: Three binary joints . In a kinematic chain, a quaternary joint is equivalent to three binary joints.
