Discussion Overview

The discussion revolves around calculating torque for a bent lever, specifically comparing two diagrams to determine which configuration yields the correct torque calculation. The focus includes conceptual understanding of torque in relation to lever mechanics.

Discussion Character

  • Conceptual clarification, Debate/contested

Main Points Raised

  • One participant questions which of the two diagrams correctly represents the torque calculation, indicating a need for clarification.
  • Another participant asserts that the bent nature of the lever does not affect the torque calculation, emphasizing the importance of the perpendicular distance from the force's line of action to the pivot.
  • A subsequent post clarifies that while the force (N) remains constant, the distance (X) varies between the two cases, which could influence the torque.
  • One participant suggests that to maximize torque for a given force, the force should be applied perpendicularly to the line connecting the lever's end to the pivot, although neither diagram illustrates this clearly.

Areas of Agreement / Disagreement

Participants express differing views on the relevance of the bent lever to torque calculations, with some agreeing on the importance of the perpendicular distance while others focus on the specific configurations presented in the diagrams. The discussion remains unresolved regarding which diagram is correct.

Contextual Notes

The discussion highlights potential ambiguities in the diagrams and the definitions of torque, as well as the assumptions regarding the application of force and its direction.

to calculate the torque (N*x) which one is correct? the one on top, or below.

I don't understand the question. The fact that the lever is bent doesn't matter. To find the torque, you want the perpendicular distance from the line of action of the force to the pivot. If N and x are the same, the torque is the same for both diagrams.
 
sorry the diagram is unclear, but the X is different for the first case, and the second case, N is the same.
 
but anyway, i think i understand it now, thanks!

I think I know what you're asking. Imagine a straight line connecting the end of the lever to the pivot. To maximize the torque for a given force, you want the force to be perpendicular to that line. (Neither diagram shows that.) That will maximize your value for X.
 
thanks for your help!
