● A mechanismon linkageis obtained if
one of the links of a kinematic chain is fixed.
●A redundant chain does not allow any motion of a link relative to the other.
We know that,
LHS > RHS
(Locked chain Non-kinematic chain
frame)
●If one of the links of a redundant chain is fixed, it is known as a structure or a locked system.
●The degree of freedom of a structure or a locked system is zero.
&Key Points:-
If,

DOF
= 0
DOF<
