Finding Moment About Any Point: Fixed Moment Value?

Click For Summary
SUMMARY

The discussion centers on the concept of calculating the moment about any point in a system, specifically when a fixed moment value, such as 50 Nm, is given. Participants confirm that if the moment is a couple, its value remains constant regardless of the reference point. The parallel axis theorem is referenced as a relevant tool for understanding these principles, particularly in relation to moments of inertia and force moments.

PREREQUISITES
  • Understanding of moment calculations in physics
  • Familiarity with the parallel axis theorem
  • Knowledge of force and torque concepts
  • Basic grasp of moments of inertia
NEXT STEPS
  • Study the parallel axis theorem in detail
  • Explore the relationship between force and moment in mechanical systems
  • Learn about moments of inertia and their applications
  • Investigate practical examples of fixed moments in engineering problems
USEFUL FOR

Students and professionals in physics and engineering, particularly those focused on mechanics and structural analysis, will benefit from this discussion.

The formula to find the moment about anypoint is
Fxr right? but if the moment is given, for example 50Nm
then the moment is fixed right? even if we change the regarding point
on the system, the given moment is 50Nm regardless what point we are regarding to.
Am I right?

Hi 385sk117! :wink:

If it's a couple (ie, a pair of equal and opposite forces), then yes, its moment is the same about any point. :smile:

Use parallel axis theorem. …

That would be for a moment of inertia …

this one is in Nm, so I 'm assuming it's a moment of force.
