The Grubler’s criterion for determining the degrees of freedom (n) of a mechanism having plane motion is
(a) n = (l – 1) – j
(b) n = 2(l – 1) – 2j
(c) n = 3(l – 1) – 2j
(d) n = 4(l – 1) – 3j
I have been asked this question in final exam.
Origin of the question is Mechanism in portion Simple Mechanisms of Machine Kinematics
