Why Series A preferred than Series B for large size flanges?
Series A flanges are having more allowable stress values than series B flanges. Hence considering design allowables, series A flanges are more preferred. Series B flanges are compact in nature and both series flanges having different PCD. Hence before procurement of interface flanges on any equipment, make sure for mating flange series.Read More…
IT CAN APPLY POSITIVE + THE NEWTON III LAW AS A CYCLE SYSYEM ON AN MOTOR ENGINE DEVICE?
Retrodynamic Effect = DextroGiro => VS VS VS <= Reaction
Action + Reaction = Retrodynamic Newton's Third Law of Motion/III: For every reaction there is an equal and opposite reaction. It is the sum of both (two) Forces in one System.Read More…
