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 Two lower pairs and one additional link Any one of these One lower pair and two additional links Two lower pairs and two additional links Two lower pairs and one additional link Any one of these One lower pair and two additional links ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine A rigid body possesses ________degrees of freedom Six Four One Two Six Four One Two ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine The static balancing is satisfactory for low speed rotors but with increasing speeds, dynamic balancing becomes necessary. This is because, the Effects of unbalances are directly proportional to the speed Unbalanced couples are caused only at higher speeds Unbalanced forces are not dangerous at higher speeds Effects of unbalances are proportional to the square of the speed Effects of unbalances are directly proportional to the speed Unbalanced couples are caused only at higher speeds Unbalanced forces are not dangerous at higher speeds Effects of unbalances are proportional to the square of the speed ANSWER DOWNLOAD EXAMIANS APP
