I Calculating Mass Inertia Product - Examples 1 & 2

AI Thread Summary
The mass inertia product is calculated by considering the shape and orientation of the object in question. In the provided examples, different methods are used to determine the moments and product of inertia for a cylinder. The discussion emphasizes the importance of accurately identifying the geometry and alignment of the object to ensure correct calculations. Clarity on these factors is crucial for achieving precise results in mass inertia product calculations. Understanding these principles is essential for applications in physics and engineering.

That's it, I got it, thank you!
 
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...
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...
