Homework Help Overview

The discussion revolves around the parallel axis theorem and its application in determining moments of inertia about various axes. The original poster is tasked with a true/false question regarding the theorem's validity when the moment of inertia about a perpendicular axis through the centroid is known.

Discussion Character

  • Conceptual clarification, Assumption checking

Approaches and Questions Raised

  • The original poster asserts that the statement is true based on their understanding and seeks reinforcement for their answer. Another participant questions the terminology, asking if "parallel axis" is synonymous with "arbitrary axis." There is also a mention of a potential misunderstanding regarding the term "perpendicular."

Discussion Status

The discussion is ongoing, with participants exploring different interpretations of the question and terminology. Some guidance has been offered regarding the importance of precise language in understanding the theorem.

Contextual Notes

The original poster has indicated a limitation of having only one attempt to answer the question, which adds pressure to their need for clarification.

Homework Statement



I am doing an assignment where I have this (easy) true/false question.

The parallel axis theorem can be used to find moments of inertia of an object about arbitrary axes, provided the moment of inertia about a perpendicular axis through the centroid of the object is known.

Homework Equations



T=rf

The Attempt at a Solution



Ok, by definition this is true. And from what I understand this is what the parallel axis theorem does. I am reviewing the concept in my textbook.

But I only have one try for this.. it would be great if I could get some re-enforcement for my answer!

Is a "parallel axis" the same as an "arbitrary axis"?

wow i am dumb
 
Well I read "perpendicular" as "particular" - you have to watch those.
That was probably the one you were supposed to notice.
