Given :Number of links (l) =2
Number of binary joint (j) = 1
Number of higher pair (h) = 0
Applying Grubler’s equation of degree of freedom,
DOF = 3l - 2j
Note : In this question formula used for, DOF is 3l - 2j, not calculating 3(l - 1) - 2j, because this function is used when one link of mechanism is fixed.
F = 3 X 2 - 2 X 1= 6 -2
F = 4
Hence, the correct option is (C).
&Key Points:-
Degree of freedom (F) :
● F = 0(Frame/ structure)
● F = 1, - 2, -3, (Cups structure)
● F = 2,3,4 (Unconstrained chain)
