Consider the Grubler’s equation for the planar mechanism given below
F = 3(n - 1) - 2j.
What does the variable n represent in the above equation?
Number of link
Number of lower pairs
Number of mobile links
Length of the longest links
Number of link
According to the equation given in the question,
F = 3(n - 1) - 2j
Where, F = Degree of freedom
n = Number of link
j = Number of binary joints.
Hence, the correct option is (A).
