thanks FEA way! Thanks, Mark

Is there a way to find the area of a face in .cae? Thanks Thanks, Mark

What does it mean that CO2 levels were so much higher several hundred million years ago (>2000 ppmv)? Is this true? How do we relate that to today 410 ppm? Thanks, Mark

Does anyone know what the benefit would be if we could extinguish coal mine and coal seam fires? I understand that just one can be large enough to emit as much greenhouse gases as all the cars in the US. It seems that a concerted effort by the international community could put a significant dent...

Could anyone suggest references for validation of FEA with metal plasticity. Thanks, Mark

My apologies rb1957, I did not include enough context for the Kulak quote. The explanation is in regards to pre-loaded bolts under pure shear testing. Tension pre-loading to levels near yield did not reduce the pure shear failure loading. Thanks, Mark

A rational from Kulac, et.al. 2001, is consistent with the comment by hydtools above. "Measurements of the internal tension in bolts in joints have shown that at ultimate load there is little preload left in the bolt. The shearing deformations that have taken place in the bolt prior to its...

rconnor, Thanks for you thoughtful reply. I am about 90% sure that the world is warming. My concern is that the minute I find a good story, someone refutes it. Regarding "group think". Keep in mind that the scientific community accepted Aristotle's Spontaneous Generation theory for over a...

We may be missing the real point. The question is not whether there are trends in the data. The world has to have warming and cooling trends. There are too many variables. As an example, I once saw a NOAA paper that concluded that the cyclical nature of space dust could result in 30% of...

ResearchEngineer987's "Because of my leasing/living arrangement and personal situation" My recommendation is not to let a temporary circumstance influence a decision that could affect a lifetime. I wish you well, Mark Thanks, Mark

@fel3, I thought it was spherical cows? Thanks, Mark

Could a charcoal filter on each of these homes (<$200/home) stop the problem? Thanks, Mark

What if there was a technical person that told the Governor what he wanted to hear? Isn't that a worse crime? Thanks, Mark

BTW, Does anyone know why the Flint river is so polluted in the first place? Thanks, Mark

rconnor, We need your educated eye on this report: https://wattsupwiththat.files.wordpress.com/2015/12/agu-poster-watts-website-release.pdf One of the conclusions... "We believe the NOAA/NCDC homogenization adjustment causes well sited stations to be adjusted upwards to match the trends of...
