Homework Help Overview

The discussion revolves around the impact of the shape or profile of a moment arm on the torque generated at an axle or fulcrum point. Participants are examining the relationship between lever shape and torque, particularly in the context of complex lever systems influenced by gravity.

Discussion Character

  • Exploratory, Assumption checking, Conceptual clarification

Approaches and Questions Raised

  • Participants are questioning whether the shape of the moment arm affects torque, with some suggesting that it does not. There are inquiries about how gravitational forces influence the torque when the moment arm is attached to an axle and experiences downward movement.

Discussion Status

The discussion is ongoing, with participants exploring different scenarios related to the moment arm and torque. Some guidance has been provided regarding the initial question, but further clarification is sought on the implications of gravitational effects and the mechanics of lever movement.

Contextual Notes

Participants are working with sketches to illustrate their points, and there appears to be some confusion regarding the arrangement of the lever and its movement, which may affect the understanding of the problem.

The shape does not matter. Your diagram is correct.
 
Thanks. So what if the moment arm is attached to an axel (depicted in the drawing as a dot) while at the same time being pulled downward by gravity. How does that downward, rotational movement affect the torque at the axel. Thanks.

I'm not seeing how that is a different scenario from that depicted in your original diagram.
Can you explain more clearly what this second scenario is?

A question: how is it arranged that the outer part of the lever remains horizontal as the inner part rotates?
