Homework Help Overview

The discussion revolves around the effects of an applied force on the rotation of an axis (M-N) when points A and B can slide within a fixed circle. The original poster seeks to understand whether the applied force will cause rotation and what modifications might be necessary if it does not.

Discussion Character

  • Conceptual clarification, Assumption checking

Approaches and Questions Raised

  • The original poster attempts to analyze the moments generated by the applied force at points A and B, suggesting that these moments may cancel each other out, leading to no rotation. Some participants question the implications of the last line of the original question regarding potential modifications.

Discussion Status

The discussion is ongoing, with some participants agreeing on the conclusion of no rotation. However, there is a noted inquiry into the implications of the original question, indicating that further exploration of the topic may be warranted.

Contextual Notes

There is a mention of a missing diagram that may be relevant to the problem context, which could affect the understanding of the applied force and its effects.

Homework Statement


A force F is applied over axis M-N in the such shown position. Both of points A and B are not fixed, and can slides inside the black fixed circle. will the applied force (in the shown position) cause the axis M-N to rotate ? if it is not rotating, then what modification should be made?

Note that the distance A-M = N-B, and M-N's length is double the length of A-M.

Homework Equations


M = F*r

M: Moment
F: Force
R=distance

The Attempt at a Solution



the force will generate equal moments at both points A and B. Anyhow, both of them will cancel each other, and thus no rotation will occur.

What do you think mates?[/B]

If you intended to post a diagram, none is showing up.

I agree. No rotation. What about the last line of the question?
