Practical Applications of Angular Momentum in Systems

AI Thread Summary
Angular momentum plays a crucial role in understanding the rotational dynamics of systems, particularly in applications like aircraft design. It helps predict how an aircraft will respond to external forces, influencing stability and control during flight. Knowledge of angular momentum allows engineers to calculate the effects of torque and external forces on an aircraft's rotation. This concept is essential for ensuring safety and performance in aerospace engineering. Ultimately, angular momentum is a fundamental measure of an object's rotational motion and its resistance to changes in that motion.

Hi all,

Just a quick question about what practical uses knowledge of the angular momentum of a system has? For example, in an aircraft system, what would the angular momentum vector be utilised for? It seems like a kind of quasi-theoretical term that has minimal purpose, but I doubt this is the case in real-world use. If the angular momentum is known, can this then be used to calculate external forces on the system which affect rotation, for example?

Thanks!

I guess, looking at the linear momentum equivalent, then the angular momentum is a measure of whether the object will continue rotating when an external force is applied to the object? Is this effectively what angular momentum represents?
 
Thread 'Is 'Velocity of Transport' a Recognized Term in English Mechanics Literature?'
Here are two fragments from Banach's monograph in Mechanics I have never seen the term <<velocity of transport>> in English texts. Actually I have never seen this term being named somehow in English. This term has a name in Russian books. I looked through the original Banach's text in Polish and there is a Polish name for this term. It is a little bit surprising that the Polish name differs from the Russian one and also differs from this English translation. My question is: Is there...
This has been discussed many times on PF, and will likely come up again, so the video might come handy.

Hi there, im studying nanoscience at the university in Basel. Today I looked at the topic of intertial and non-inertial reference frames and the existence of fictitious forces. I understand that you call forces real in physics if they appear in interplay. Meaning that a force is real when there is the "actio" partner to the "reactio" partner. If this condition is not satisfied the force is not real. I also understand that if you specifically look at non-inertial reference frames you can...
