●According to the definition of degree
of freedom, “the number of independent variables required to define motion or
position of the system”. So in screw pair both motion (rotation and transition)
are dependent on each other. That is why, it has 1 degree of freedom.
Hence, the correct option is (C).
&Key Points:-
●Remember that a particular relative
motion between two links of a pair must be independent of the other relative
motion that the pair can have.
●In screw and nut pair, the two
motions cannot be accomplished independently.
