This equation is called Kutzbach criterlon for the movability of a mechanism having plane motion. Note: If there are NO two degree of freedom pairs (i.e. higher pairs), then h = 0. We have (it) n = 3 (I- 1) – 2j

I need the answer as soon as possible
![This equation is called Kutzbach criterlon for the movability of a mechanism having plane
motion.
Note: If there are NO two degree of freedom pairs (i.e. higher pairs), then h 0. We have
(it)
n = 3 (1-1)- 2j
It may be noted that
(a) When n= 0, then the mechanism forms a structure and no relative motion between the links
is possible, as shown in Fig. (a) and (d).
(6) When n= 1, then the mechanism can be driven by a single input motion, as shown in Fig. (b).
(4 When n= 2, then two separate input motions are necessary to produce constrained motion
for the mechanism, as shown in Fig. (d.
(d) When n=- 1 or less, then there are redundant constraints in the chain and it forms a
statically indeterminate structure, as shown in Fig. (e).
