Comments03/08/2017 #37 Phil Friedman#30 I agree entirely, Milos, Science and Engineering aren't always just about the "big" stuff, but just as often about understanding and improving the "little" things in life -- like, as you point out, how deep-cycling cell phone batteries reduces their working life.03/08/2017 #36 Phil Friedman#34 Peter> "I'm trying to establish that the term "value engineering" is not a universally understood term.."
Ah, Peter, if you had only said that at the beginning of your first comment, my eyes would not be glazing over with this exchange.
To be clear, I agree with you that the term may not have a single universally-accepted definition. But then how many such terms do?
I believe it sufficient that I used the term in one of its commonly accepted meanings. I am sorry if you mistook what the piece might be about. But it seems to me that the title clearly indicated the article was about "small solutions". Moreover, the lead image reinforces that point, especially in the simulated drawing title box, where it actually describes the object that will be the focus of attention. And if those were not enough to warn you off potential ennui, the first highlighted statement left little doubt.
"Engineering isn't always simply about the design of a product but just as often about the planning and execution of the building of that product..."
Cheers!03/08/2017 #35 Anonymous#34
1. Meaning of “value engineering” in the English Dictionary:
"The process of reducing the cost of producing a product without reducing its quality or how effective it is:
Substantial value engineering had to be done to control costs." (http://dictionary.cambridge.org/dictionary/english/value-engineering)
2. "Value Engineering (VE) is concerned with new products. It is applied during product development. The focus is on reducing costs, improving function or both, by way of teamwork-based product evaluation and analysis. This takes place before any capital is invested in tooling, plant or equipment." - from article: Value Analysis (VA) and Value Engineering (VE): Definitions and Benefits on advice-manufacturing.com (http://www.advice-manufacturing.com/Value-Analysis.html)
3. "Value Engineering is a systematic analysis method which, when properly applied to a product, process, or service, will reduce costs and increase profit margins. It involves creativity and challenges existing procedures, revealing successful new strategies. It is also known as Value Analysis. The results and techniques are the same." - from McGill University Value Engineering Workshop
4. "Value engineering can be defined as an organized effort directed at analyzing designed building features, systems, equipment, and material selections for the purpose of achieving essential functions at the lowest life cycle cost consistent with required performance, quality, reliability, and safety." - from the U.S. General Services Administration (GSA) website
(https://www.gsa.gov/portal/category/21589)03/08/2017 #34 Peter Altschuler#29 No, @Phil Friedman, I'm not trying to build a straw man. I'm trying to establish that the term "value engineering" is not a universally understood term.
Rather than being mundane, it's particularly domain-specific. So, for those of us who are not in engineering or government or nautical construction, we're far more likely to impose our own definition than yours. In such a situation, it helps to clarify the intent.
Your article is technical, and it requires a certain level of knowledge and comprehension. I don't have that and, if I'd known at the outset that it "may be of interest to engineers and tradesman who deal regularly with construction- and manufacturing-related problems and issues," I'd have focused my attentions elsewhere.03/08/2017 #30 Anonymous@Phil Friedman please continue with this series. It's gonna work.

Monash is one of Australia's leading universities and ranks among the world's top 100.
Article: "Explainer: how to extend your phone’s battery life" (https://theconversation.com/explainer-how-to-extend-your-phones-battery-life-80958)03/08/2017 #29 Phil Friedman#24 No, Peter, you're not just saying. Your seeking to build a straw man argument by assuming a definition of "value-engineering" that serves your own purposes.
To wit, a commonly accepted definition of value engineering is, "Value engineering (VE) is a systematic method to improve the "value" of goods or products and services by using an examination of function. Value, as defined, is the ratio of function to cost."
The particular example I chose here illustrates the performance of a particular operation necessary during the construction of a high-tech military vessel, under a NAVSEA government contract, at a cost far below what was expected or budgeted. Sorry, if that strikes you as too mundane to be of interest, but frankly that is the reaction of a writer who talks about such things, not that of anyone who is a shop-floor veteran, engineer or otherwise. In this context, I am happy to ...
Cheers!03/08/2017 #25 Anonymous#24 Just guess Peter, I could write an article on how to fight against hydrogen embrittlement and the environmentally-enhanced cracking of military equipment, including naval ships and fighter. This seems like a very important technological breakthrough, but it is not. Social media is not the ground for such "so-impressive value-engineered solution". Finally, an article like this one by Phil has great practical value and certainly represents a practical and useful example of a successful engineering in a specific field. Science and engineering are not only in national laboratories and large research centers. The work of engineers is also practical. Just my 2 cents.03/08/2017 #24 Peter AltschulerNah, @Phil Friedman, that ain't gonna work.
I've written about grazillions of "value-engineered solutions" that have nothing to do with any actual engineering. It's one of those, well... marketing phrases intended to make something seem oh-so-impressive.
It could be about improving operations with new technology that is engineered to simplify interactions, accelerate transactions, and improve productivity because, yes, it's value is engineered-in. Or about a ship whose hull design is so advanced that it slips through water with less drag than a dolphin and, as a result, uses less fuel, increases speed, and reduces onboard manhours, all due to the fact that it's value-engineered.
I'm just sayin'.03/08/2017 #23 Phil Friedman#8 Thanks, @Todd Jones, for reading and the kind words. Plugs for the intake holes were placed in the female tool by working from the CAD drawings. A male plug placed in a female tool leaves a hole in the molding when it is removed from the tool. Same for the waterjet drives, which were inserted through holes in the transom. We built special purpose alignment jigs for the intake grates which had a vertical spike that extended up into the hull and which had to kiss a laser light beam from a jig on the transom in order for us to know that the waterjet units could be buckled up to the intake ducts/grates.
A lot of measuring, laser projecting, etc. However, you need to keep in mind that the only really tricky part was to assure that the drive would couple properly to the intake ducts because the engines were coupled to the drives via Cardan shafts (a long jack shaft with a constant velocity universal joint at each end.

What I've discovered, however, is that simultaneously sharing a piece in a number of groups breaks up the "trending" stats among the group notices and tends to retard distribution in the main feed. (LI worships trending and so gives better distribution to what the Algirithm sees as more popular articles.)
So better to wait for sharing into groups until the initial rush of views and likes is complete and the piece sits on the LI "long tail".

So much has been said and written about la Sagrada Familia and its creator. It's the world’s longest running construction project.
In the 60's Le Corbusier was trying to modernize Gaudi’s designs, suggesting his work had become irrelevant. But his campaign had been fortunately unsuccessful.

I must admit to having a matter of fact attitude towards large stony edifices, after having been overexposed to them and to their religious disorders from an early age. But this spike-ridden magnificence certainly grabs the attention, with its detail so copious as to appear from a distance as almost random.

- 19/07/2017USING GRAVITY FOR BUILDING ARCHES LIKE THE ANCIENT ROMAN BUILDERS DID ►
The Arch-lock system uses gravity for joinery! The precast concrete blocks are used for building the strong free-standing structures like tunnels, overpasses or storage sheds without the need for mortar.
Comments22/07/2017 #7 Phil Friedman#6 Thank you, Lada, for your detailed answer. My questions were more than idle curiosity, as I have professional interest in the science of string materials and the associated engineering of structures that take best advantage of those modern materials. But the fact is one cannot fully appreciate strong materials and engineering for minimum weight unless one has an appreciation for structures such as the Roman arch. Cheers!22/07/2017 #6 Lada 🏡 Prkic#4 (Sequel to my previous answer)
Yes, we are in the age of the strong materials such as steel and prestressed concrete that allow construction of much larger arches than the ancient Romans did. But the fact is that these ancient arch bridges and aqueducts still standing today and they survived despite seismic activities throughout the centuries, which many modern buildings didn't.
We can't build arches like that anymore because the method of construction is both material and labour intensive. The massive falsework was required to support all parts of the structure, which has no stability prior to the insertion of the keystone on the top of an arch.
That's why I see many benefits of this modern and improving approach to the true Roman arch. 1.) This method eliminates falsework. 2,) Interlocking design holds the precast concrete voussoirs together during and after assembly and eliminates the need for mortar.
I read about some project in Canada where the Arch-Lock system would be used, as a low-cost vaulted tunnel on the railway line that would allow the construction of the highway directly over.
As for bonding the wedge-shaped stones together, the Romans had used the slow setting mortar and some kind of shimming to overcome dimensional irregularities of cut stone voussoirs.21/07/2017 #5 Lada 🏡 Prkic#4 Phil, first, I admire you as a commenter because your questions always provoke further engagement with the post. I'm glad you find this topic interesting. I'm also glad that there are people (though, very few) who will engage in such "engineering" topics, commenting on its core. :-)
This is the first part of my response. I'm writing this while drinking my morning coffee before going to work. I'll continue in the afternoon. Regards21/07/2017 #4 Phil Friedman#3 The Roman arch is, of course, fascinating, being able as it is to transfer all the loads in such a way as to hold itself together and stable, as well a support external loading at the same time. But, here are a couple of questions I still have:
1) Does bonding the component stones together have any beneficial effect on the arch's ability to withstand loading? Has anyone ever experimented with that?
2) In this age of the science of strong materials and the techniques of creating structures that dispose strength-contirbuting cross-section where it does the most work underloads, outmode the true arch which is a pure compression structure?20/07/2017 #3 Lada 🏡 Prkic#1 Phil, thanks for stopping by and commenting. :-)
I've been interested in Ancient Roman architecture for a long time. The Roman arch has had a lasting impact on architecture all the way to the present time.
Both the angle and the number of wedge-shaped stones (voussoirs) have an effect on the strength and stability of an arch. For the semicircular arch, it seems that an "ideal" angle is when 180 degrees divides into 11 sectors, at about 16 degrees each.
It is the number of concrete wedge-shaped elements in the post picture.

- 19/06/2017THE WORLD’S FIRST TRULY TRANSPARENT SOLAR TECHNOLOGY
The MIT researchers have created a truly transparent solar panel that can coat any surface, to harvest ambient light and generate electricity.
The transparent photovoltaic (PV) cell absorb only infrared and ultraviolet light. The visible light passes through, unimpeded. Because the material does not absorb or emit light in the visible spectrum, it looks exceptionally transparent to the human eye.
I look forward to seeing its application on tall buildings with lots of windows or glass facade in the near future.
Comments20/06/2017 #5 Phil Friedman#4 Wow, Lada, that is huge. By my calculations an average house here in the U.S. has nearly 1,000 square feet of windows. At 10 watts per s.f. during an 8-hour day, at 50% efficiency that's 40 Kwh per day.in sunny climes. And if the "glass" actually captures infrared light, it will reduce the greenhouse effect and lower the heat loading in the house. That is certainly not anything to sneeze at. Cheers!19/06/2017 #4 Lada 🏡 Prkic#1 Yes, you're right, Phil. It's hard to say how much power could be generated. The power-conversion efficiency is expected to reach over 10% once production commences, but the prototype has an efficiency about 1%.
A rough calculation that I found says that 1% efficiency means about 10-12 watts per square meter or about 1 watt per square foot.
But fully optimized it would generate about 10 watts per square foot!
- 15/06/2017as a material engineer I must share this graphic where you can find the difference between a regular ACM material and a Fire resistant one. this is one of the two cladding materials I found on the website of Harvey facade: Alucobond(r) and Reynobond(r).
only because you manage, shape and install a material does not necessary mean you really know deeply about it; materials behavior is complex and as materials engineer and scientist we studied years to start knowing something about.
ignorance about materials selection is very dangerous because increases the probability of an accident.
the right material selection could help preventing similar tragedy #grenfell #fire #materialsengineering #materialselection
