I used to have some machines with Fanuc 6 controllers circa 1981 - 1983. They had variables, macros, branching, etc. I haven't been able to find what processors were in those old controllers, but I'm certain the single board com

I'm not sure what you thought was contradictory within that quote. I thought it was reinforcing a single idea? I was pushing back on the idea that very high reduction ratios keep causing higher and higher strength. There is a pretty

I think it is unfortunate the US government got rid of all their MIL and STD standards. You used to have a rich resource of technical specifications for materials, fasteners, fittings, etc for free access. Now they are pretty well all can

Thanks for slogging through that one to find an example. I've come across that handbook before, and went looking through it in the alloys I normally work with. In the alloys I normally see, the L and LT are either identical, or with

I'm not saying grain flow doesn't exist. My claim is that I can't find any support for the idea that grain flow results in superior strength characteristics in the grain direction.

by abe_m 2y ago
I'd really like to see some backing of these claims. I've seen "grain flow" claiming big gains for years in various enthusiast magazines (bike, motorcycles, cars, etc) as to why components are forged. Then I started wor

We have a few convenience stores in my city that have started offering a small selection of fresh foods, something like a little basket with a few apples, oranges, and bananas. Some of them have expanded out into a full produce section. O

by abe_m 3y ago
That's a lot of words to say that fresh foods aren't available close by because people don't want them. They are demanding convenience foods with their dollars, so that is what the vendors provide. Forcing a store into exis

Was this effort at the request of residents of this food desert? Or was this an initiative of people outside of the area the proposed stores would serve?

by abe_m 3y ago
If people in the area generally wanted vegetables, someone would sell them. So the most likely case is that the vast majority of people in food desserts don't really want vegetables.

These same guys are building a commercial heavy-haul, vocational targeted diesel-electric hybrid truck. Their plan is to run a diesel at about half the normal displacement, and have batteries for a few hundred km of range. The axles are e

First of all: I fully agree with you. The calculation should be listed explicitly in the mortgage documents. I've also struggled through figuring it out on my own, and the two things that got me to less than a dollar of difference wer

In Ontario (perhaps other provinces as well), train drivers (engineers), and operating engineers, are allowed to continue using the "engineer" name for their jobs, but not "professional engineer". Those two were well es

Engineering societies in Canada are not really private. They are considered self-regulating professions, where the society has an official role regulating their profession. Each of the provinces have enabling legislation that authorizes t

Refrigerant based systems aren't bounded by Carnot efficiency. Yes, I mean Coefficient of Performance. It is directly equivalent to efficiency. I don't understand how this thermal capacitor arrangement works, but if they're

by abe_m 3y ago
Quite a misleading article. They say it has the potential to be "highly efficient" in the intro. But later say it can achieve 64% of it's Carnot efficiency. If we assume their max 21C temp differential is from 20C to 41C,

I suppose it isn't, but I bristle when I see someone tossing around statements like "close enough doesn't really exist". In my experience when statements like that start up, there are people involved that don't und

It is interesting how closely the proposals of Gesell are to current US Fed policy of 2% inflation. The main difference seems to be the current system runs on the Cantillion effect, where those in favoured positions (close to where the mone

When the cost of RAM is on Microsoft's balance sheet, perhaps that will change their priorities for reducing resource consumption of their software.

VAT = Value Added Tax When the input cost of something increases in the supply chain (prior to sale to consumer), the buyer doesn't pay VAT on the input. So if the input costs $10, and there is s 25% VAT, the buyer pays $12.50, but th

That paper is comically bad. Coal is the backbone of many grid systems, and a real part of what people pay for electricity. Somehow they call coal "uneconomic" without defining any standard by which the define economic. How is
