Discussion Overview

The discussion revolves around solving for the moment of torque in a mechanical system involving a two-bar structure. Participants seek clarification on the problem statement, including the dimensions and units involved, as well as the relationship between the torques produced by different forces.

Discussion Character

  • Exploratory, Technical explanation, Debate/contested

Main Points Raised

  • One participant requests the complete problem statement and clarification on the units used in the calculations.
  • Another participant questions the relationship between the counterclockwise (CCW) torque produced by a force of 11.27 and the clockwise (CW) torque produced by a force of 300, suggesting that the effective lever arm for torque T is about 0.7 times that of the 300 force.
  • A further comment highlights that the ability of the force of 11.27 to counteract the force of 300 is contingent on the units being used.

Areas of Agreement / Disagreement

Participants have not reached a consensus, as there are multiple competing views regarding the effectiveness of the torques and the importance of unit definitions.

Contextual Notes

There are limitations regarding the clarity of the problem statement and the definitions of units, which may affect the understanding of the torque calculations.

Who May Find This Useful

This discussion may be useful for individuals interested in mechanical engineering, physics, or anyone working on torque-related problems in structural systems.

Homework Statement
I have problem on T, is it T is clockwise so the answer is negative?
Relevant Equations
My answer is: M(A)= (Tv x 25)+(Tn x 15)-(300x40)

0=(T sin(5/13)) +(T cos(12/13))- 10200

T=11.27

Please clarify my answer, thank you

Welcome to PF.

Can you please provide the complete problem statement? Is that a 2-bar mass of some sort, welded at the join? It looks like the dimensions are in imperial units (feet, inches), what are the force units in? What are the units in the calculations you have shown?
 
Welcome, Andy! :cool:

Why (300x40)?

Intuitively, do you believe that the CCW torque produced by 11.27 can counteract the CW torque produced by 300?

Note that the effective lever of T is about 0.7 the lever of 300.

Well, technically, it depends on the units, eh? :wink:
