Which of the following is NOT
classified as types of link?
Rigid link
Flexible link
Fluid link
None of these
None of these
Links should not be necessarily rigid
but should be resistant body, capable of transferring motion.
Hence, the correct option is (D).
&Key Points:-
●A body is said to be rigid if under
the action of forces, it does not suffer any distortion or the distance between
any two points on it remains constant.
●Some semi-rigid bodies which are
normally flexibility but under certain loading conditions act as rigid bodies
for the limited purpose and thus are resistant bodies.
●A belt is rigid when subjected to
tensile forces. Therefore, thebelt-driveacts as a resistant body.
●Fluids can also act as resistant
bodies when compressed as in case of a hydraulic press.
