Folks,(adsbygoogle = window.adsbygoogle || []).push({});

Consider a 2d disk with 2 forces ( ie a bolt pattern) acting axially ie into the page. One can easily get the equivalent force and its point of application to represent the given force system.

One can do the same with an annulus, get an equivalent force and its point of application etc.

However, I have a calculation where the resultant point of application is at a radius smaller than than the inside radius of annulus.

This is no good to me because I need to apply the load physically on the FEA model.

So it appears it is not possible to do this since the calculations are independent of the geometry.....

Opinions?
