Discussion Overview

The discussion revolves around the definitions and distinctions between axial and radial moments, specifically in the context of torque. Participants explore the conceptual understanding of these terms and seek clarification on their applications and implications.

Discussion Character

  • Conceptual clarification
  • Debate/contested

Main Points Raised

  • Some participants inquire about the definitions of axial and radial moments.
  • One participant references a Wikipedia article on polar moment of inertia but seeks further clarification.
  • There is a question regarding whether torque is classified as an axial or radial moment.
  • One participant argues that torque is not a moment in the sense described in the referenced article, noting a difference in dimensions and suggesting that torque is a product of arm and force.
  • Another participant expresses a preference for classifying torque as 'axial' rather than 'radial', while emphasizing a preference for the term 'moment' alone.
  • A participant explains that torque is a pseudovector that points in an axial direction, suggesting that the term 'radial' could imply a perpendicular direction to the axis.
  • There is a request for everyday examples of axial and radial moments to aid understanding.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the classification of torque as either axial or radial, and differing opinions on the terminology and conceptual understanding remain evident throughout the discussion.

Contextual Notes

Some participants express personal considerations regarding the terminology used, indicating that definitions may depend on context and interpretation. There is also an acknowledgment of potential language differences in the use of 'torque' and 'moment'.

Hello can someone explain what is axial and radial moments?
 
Physics news on Phys.org
Yes...wanted some info otherwise
 
Thought as much. So now we come to your question: what is your question ?

Is torque an axial or radial moment?
 
Torque is not a moment in the sense of the moments in the link in post #2. (You can see this from the difference in dimensions).

It is a moment in the sense of arm x force. In many languages torque and moment are synonyms.

If forced to make a choice, I would choose 'axial' instead of 'radial', but strong preference for me is on just 'moment'.

Why axial and not radial
 
Torque is a pseudovector that points in an axial direction. So I would want to avoid the term 'radial' in its neighborhood: that suggests something that points perpendicular to the axis.

(I grant that this is a personal consideration, but perhaps others share it).

Can you give me daily life examples of axial and radial moments for my understanding?
