In higher pair, the relative motion isa)purely turningb)purely sliding...
When the two elements of a pair have a line or point contact when relative motion takes place and the motion between the two elements is partly turning and partly sliding, then the pair is known as higher pair. A pair of friction discs, toothed gearing, belt and rope drives, ball and roller bearings and cam and follower are the examples of higher pairs.

In higher pair, the relative motion isa)purely turningb)purely sliding...
In higher pair, the relative motion is a combination of sliding and turning.
Explanation:
Higher pair refers to a type of mechanical joint where the contact between two elements is made along a line or curve. This is in contrast to lower pair, where the contact is made along a point or surface.
When two higher pair elements are in contact, their relative motion is a combination of sliding and turning. This means that as one element slides along the surface of the other, it also undergoes a rotational motion.
Sliding Motion:
Sliding motion refers to the linear movement of one element along the surface of another. In the case of higher pair, this sliding motion occurs as one element slides along the line or curve of contact with the other element.
Turning Motion:
Turning motion refers to the rotational movement of one element with respect to the other. In the case of higher pair, this turning motion occurs as one element rotates about an axis with respect to the other element.
Combination of Sliding and Turning:
In higher pair, the relative motion is a combination of sliding and turning because both types of motion occur simultaneously. As one element slides along the surface of the other, it also undergoes a rotational motion. This combination of sliding and turning is characteristic of higher pair joints and allows for a greater range of motion and flexibility compared to lower pair joints.
Example:
A common example of a higher pair is a cam and follower mechanism. In this mechanism, the cam is the rotating element that imparts a sliding and turning motion to the follower. As the cam rotates, the follower slides along the surface of the cam and also undergoes a rotational motion. This combined motion allows the follower to follow the contour of the cam and transfer motion or force from the cam to another part of the mechanism.
