Ina four-barlinkageif ‘S’ is the length of the shortest link, ‘L’ is the length of longestlink and ‘P’ & ‘Q’ are lengthofotherlinks, then the criteria for getting a triple rocker mechanism in which no links will fully rotate is.

A

$$S + Q > P + L$$

B

$$S + L < P + Q$$

C

$$S + L = P + Q$$

D

$$S + L > P + Q$$
