Dynamic properties
hi allWhat value can be used for coefficents of friction (static and kinetic) and restitution in dynamic analysis.Does it depends on rpm.Also suggest a book if it has addressed such question.Thanks

Re: Boundary Condition on Internal Surface?
Paul, Good question and I am not exactly sure what Mechanica is doing internally when this happens, if the conduction or convection overrides one or the other, or is some type of interpolation is...

Hello Everybody, I am working with Pro mechanica, I am seeing singularity in my results. what is meant by singularities? It's the peak stress as for I know, but still I could not understand exactly....
View ArticleRe: Singularities in FEM results!
A singularity is a point, usually with a load applied which means that the stress is undefined or infinite. http://en.wikipedia.org/wiki/Mathematical_singularity If you have a singularity, the analysis...

If this is a simple system (two spur gears, two bearings on each shaft) then it's trivial to calculate the gear mesh forces, assuming you know the working pressure angle, and convert them into simple...

Did you try to search for "singularities" in the Help Center ? The explanation found in the Help Center is quite clear.
