Homework Help Overview

The discussion revolves around a problem related to moments of inertia, specifically identifying different components (IA, IB, IC) and applying the formula for calculating moments of inertia. The original poster expresses uncertainty about how to approach the problem due to a lack of specific information regarding the components.

Discussion Character

  • Exploratory, Assumption checking

Approaches and Questions Raised

  • Participants discuss the identification of components based on their arrangement and question the criteria for categorizing the problem as Introductory versus Advanced. The original poster seeks hints on how to begin solving the problem, while others suggest starting with the leftmost component and considering the mass and distance from the axis.

Discussion Status

The discussion is ongoing, with participants exploring different interpretations of the problem setup and offering guidance on how to approach the calculations. There is no explicit consensus on the definitions or classifications, but some productive direction has been provided regarding the initial steps to take.

Contextual Notes

There is a noted lack of specific information about the components involved in the problem, which is causing uncertainty in the discussion. Additionally, there are procedural questions regarding the categorization of the thread within the forum.

I= ∑ miri^2 ?

The Attempt at a Solution



I'm not sure on how to start this problem. How exactly do I know which one is IA, IB, IC since it didnt specify? Can somebody please hint me in solving this problem?

There's no way to know for sure, but I would guess they are A, B, C from left to right.
By the way, this belongs in Introductory, not in Advanced.
 
Oh I'm sorry about that, how do I move the thread over? Kinda new to this.

I don't know whether you can. Might need a Mentor for that. But don't worry about it this time.. just consider it next time.
Not sure what the exact definition of Advanced is here, but if you look around the other posts you'll get the flavour.

Ah okay. Do you think you can help me with the question though? I'm not really sure where to begin.

Let's start with the leftmost picture (A, presumably). There is only one mass. What is the mass, and how far is it from the axis? What does the ∑miri2 formula give you?
