A kinematic chain is known as a mechanism when
A. None of the links is fixed
B. One of the links is fixed
C. Two of the links are fixed
D. None of these
Answer: Option B
Solution(By Examveda Team)
A kinematic chain is a combination of links connected in a specific order, allowing relative motion between them. When one of the links in a kinematic chain is fixed or stationary, it is termed a mechanism. This fixed link provides a frame of reference against which the motions of other links are observed. The fixed link is often referred to as the "ground" or "frame" link, and it serves as a foundation for the movement and analysis of the remaining links in the kinematic chain.By fixing a single link, the entire kinematic chain becomes a functional system with controlled or constrained motion. This is a fundamental concept in the study of mechanisms, which are essential components in various mechanical devices and machines used in engineering applications.
Note: Options A and C are not accurate because the presence of fixed links is essential to define a mechanism. Option D is also not correct as one of the options (Option B) is indeed the correct condition for a kinematic chain to be termed a mechanism.

why one of the links is fixed
When one of the kinematic links is fixed in a kinematic chain, then the chain is known as the Mechanism. Usually, a kinematic chain having four or less kinematic links is known as the Simple Mechanism. A Kinematic chain having more than four kinematic links known as the Compound kinematic chain or Compound Mechanism.
if each and every link is connected with two other links then the kinematic chain formed will be
