If two moving elements have surface contact in motion, such pair is known as

(a) sliding pair

(b) rolling pair

(c) surface pair

(d) lower pair

The question was asked in exam.

This intriguing question originated from Relation Between Linear Motion and Angular Motion topic in section Kinematics & Kinetics of Motion of Machine Kinematics

Right option is (d) lower pair

The best explanation: when two elements of a pair have a surface contact when relative motion takes place and the surface of one element slides over the surface of the other, the pair formed is known as lower pair.
