Theory of Machine The relation l = (2/3).(j + 2) apply only to kinematic chains in which lower pairs are used. This may be used to kinematic chains in which higher pairs are used, but each higher pair may be taken as equivalent to Two lower pairs and two additional links One lower pair and two additional links Two lower pairs and one additional link Any one of these Two lower pairs and two additional links One lower pair and two additional links Two lower pairs and one additional link Any one of these ANSWER DOWNLOAD EXAMIANS APP
