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 calling fictitious forces not real just about terminology?'

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...

Thread 'Derivation of Hamilton's Principle: Questions'

I have recently been really interested in the derivation of Hamiltons Principle. On my research I found that with the term ##m \cdot \frac{d}{dt} (\frac{dr}{dt} \cdot \delta r) = 0## (1) one may derivate ##\delta \int (T - V) dt = 0## (2). The derivation itself I understood quiet good, but what I don't understand is where the equation (1) came from, because in my research it was just given and not derived from anywhere. Does anybody know where (1) comes from or why from it the...
