(d) sliding pair

I got this question during an interview.

I need to ask this question from Types of Links topic in chapter Simple Mechanisms of Machine Kinematics

Answer 1

Correct choice is (d) sliding pair

The explanation is: When the nature of contact between the element of a pair is such that one element can turn abut the other by screw threads, the pair is known as a screw pair. When the nature of contact between the element of a pair is such that it can only slide relative to the other, the pair is known as a sliding pair.
