The motion of a shaft in a circular hole is an example of incompletely constrained motion.
Incompletely constrained motion-When the motion between a pair can take place in more than one direction, then the motion is called an incompletely constrained motion. The change in the direction of impressed force may alter the direction of relative motion between the pair. A circular bar or shaft in a circular hole, is an example of an incompletely constrained motion as it may either rotate or slide in a hole. These both motions have no relationship with the other.

Answer is:
All of the above
Explanation:
When the motion between the elements, forming a pair,is such that the constrained motion is not completed by itself, but by some other means, then the motion is said to be successfully constrained motion.
Answer is:
A shaft in a circular hole forms a successfully constrained motion.
Explanation:
When the motion between the elements, forming a pair,is such that the constrained motion is not completed by itself, but by some other means, then the motion is said to be successfully constrained motion.
Answer is:
Sliding Pair
Explanation:
Sliding Pair: When the two elements of a pair are connected in such a way that one can only slide relative to the other, the pair is known as a sliding pair. The piston and cylinder, cross-head and guides of a reciprocating steam engine, ram and its guides in shaper, tailstock on the lathe bed etc. are examples of a sliding pair. A little consideration will show, that a sliding pair has a completely constrained motion.
