Question

1. In a four-bar linkage, S denotes the shortest link length, L is the longest link length. P and Q are the lengths of other two links. At least one of the three moving links will rotate by 360⁰ if                                         

      (a) S + L ≤ P + Q                                                 (b) S + L > P + Q

      (c) S + P ≤ L + Q                                                 (d) S + P > L + Q
