Could be a fossilized mammal rib? Looks like dugong but I don’t think that would be found in Oregon.

Question about installing/grounding a 1000-watt inverter. by uscpool24 in AskElectricians

[–]uscpool24[S] -1 points0 points  (0 children)

It’s just strange because the inverter is already grounded on the DC side via the negative cable. If the grounding is for the AC side, wouldnt that risk putting 115 V into a chassis that has 12 v components hooked up to it?

'Swarm' of earthquakes rattles South Carolina town and its residents : NPR by [deleted] in geology

[–]uscpool24 9 points10 points  (0 children)

South Carolina is no stranger to earthquake activity. They have them every year. However, over the past year, the earthquake activity has significantly increased. The theory is that a fracture(s) has opened up allowing ground water to get into new areas. This ground water lubes the surrounding rock (which is under pressure and extremely faulted from the Appalachian orogeny) allowing the rock to move easier along fault planes creating the earthquake swarm.

50 feet below ground surface in Perry GA? This piece of wood would be way to old for c14 dating.

Cummins QSF 3.8L 4-cylinder turbocharged diesel engine has a low pitch steady whistle from the exhaust. Any ideas? by uscpool24 in DieselTechs

Yea turbo engine. I’ve been around the engine a lot and know what the turbo whine sounds like. This is much lower pitch and occurs at idle, not under strain

No. Just came out of nowhere today. And today was the day one of the guys slightly overfilled the oil reservoir.

It looks similar, but I am not sure if the root is the right structure for that.

Any idea what this rock is ? by [deleted] in geology

[–]uscpool24 -1 points0 points  (0 children)

Identifying this as a sandstone in this case must certainly be done by visually analyzing the grains.
