Discuss
Answer & Solution
Answer: Option C
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.
