    Compare Forces
AI Thread Summary
To effectively compare analytical and measured forces, it's important to analyze both the individual components of the forces and their overall norms. While comparing the three components may yield significant relative errors, evaluating the relative error of the norms alongside the angles between the forces provides a more accurate assessment. The discussion highlights the context of a FEM simulation involving electromagnetic forces rather than a strain gauge experiment. A comprehensive approach that considers both norms and angles can enhance the comparison's reliability. This method is crucial for achieving meaningful insights in force analysis.

Hello

Suppose we have to compare a set of forces calculated with an analytical model to a set of measured forces.

What in your opinion is a good way to compare the forces? I have noticed that comparing the 3 components of the forces (suppose that we can measure all of the simultaneously) leads to unpleasant relative errors while expressing the relative error of the norms together with the angles between the forces gives a better results.

What do you think?

Thanks in advance and kind regards

Is this a strain gauge experiment?
 
Nope. It is a FEM simulation involving electromagnetic forces :smile:
 
You would need to explain more fully.

Thread 'Is there a white hole inside every black hole?'

This is what I am thinking. How much feasible is it? There is a white hole inside every black hole The white hole spits mass/energy out continuously The mass/energy that is spit out of a white hole drops back into it eventually. This is because of extreme space time curvature around the white hole Ironically this extreme space time curvature of the space around a white hole is caused by the huge mass/energy packed in the white hole Because of continuously spitting mass/energy which keeps...

Thread 'Is Gravity an entropic property like Surface Tension'

Why do two separately floating objects in a liquid "attract" each other ?? What if gravity is an emergent property like surface tension ? What if they both are essentially trying to *minimize disorder at the interfaces — where non-aligned polarized particles are forced to mix with each other* What if gravity is an emergent property that is trying to optimize the entropy emerging out of spin aligned quantum bits
