    Force Moment
Click For Summary

Discussion Overview

The discussion revolves around finding a force that results in zero moment at a specific point in a system involving a block with two tension forces acting on either side. Participants explore the conditions necessary for achieving this equilibrium state.

Discussion Character

  • Technical explanation, Conceptual clarification, Homework-related

Main Points Raised

  • One participant inquires about the method to determine the tension force that results in zero moment at a designated point, referred to as point O.
  • Another participant requests further clarification on the initial question posed.
  • A participant indicates that they will provide a diagram to aid understanding of the problem, emphasizing the need to find the tension T for zero moment while noting that the block is supported.
  • A later reply suggests resolving the forces into components and summing the moments about point O, implying that this approach will yield sufficient equations to solve for the unknown tension T.

Areas of Agreement / Disagreement

The discussion does not appear to reach a consensus, as participants are still clarifying the problem and exploring different approaches to finding the solution.

Contextual Notes

There may be limitations in the assumptions regarding the system's configuration, the definitions of forces, and the specific conditions under which zero moment is achieved, which remain unresolved.

how do you find a 0 moment on a system. for example if i had a block with two forces in tension either side and i know 1 tension value and i want to find the other which will cause zero moment at a point ( say O ). any ideas??

Thanks

please more expplaination
 
i'll draw a pic. i want to find T so there is zero moment at O. but the block is suported

hope you can understand that :/
 
Resolve the forces into components and sum the moments about point 0. You should end up with enough equations to solve for T.
