What is the correct answer?


The Kutzbach criterion for determining the number of degrees of freedom (n) is (where l = number of links, j = number of joints and h = number of higher pairs)

A. n = 3(l - 1) - 2j - h

B. n = 2(l - 1) -2j - h

C. n = 3(l - 1) - 3j - h

D. n = 2(l - 1) - 3j - h

Correct Answer :

A. n = 3(l - 1) - 2j - h
