Dear Diana,

I am deeply despondant that 35 pages plus a few half pages were adverts and only 41 pages were articlres, and 4 of of these were so full of maths of no use to man or beast. so are you hard stuck for articles….

How do you get that Bob, at the most I can only see 20 pages of adverts including covers and 42 of content which is about the same as the previous issues 20 pages of adds and 43 of content

Or as I think (know) is the case you are counting the Free show guide which is 16 additional pages that you don't usually get and have paid no more for.

I can't see 4 pages of maths either ?

Bob,

If i have told you once I've told you a thousand times DON'T EXAGGERATE !!

[JasonBModerator @jasonb]

JS – Must try harder

I found 5 pages of maths or 7 if you include the long formulas in the combustion article

I agree with Jason's basic point – it isn't fair to include the show guide which is an extra element that is separate from normal content AND advertising.

Nice TE on the front cover though, looked far more authentic than the glass case models!

Possibly not to man or beast, but I'd have thought they might be useful to engineers…….

What?? Actual equations and such like? An article with real stuff??

Looking forward to getting the issue over here!

(not really tongue in cheek; math rules everything we do. Well, maybe not what John Stevenson does, but at least what I do. I actually like math)

Not only but also, even a real definite integral! – Andrew

Thought this one would sort you out.

Fewer adverts = fewer pages for articles and/or more expensive magazine. Can't have it both ways, given that this has to be a commercially viable business. Unless you know something I don't….

Take it or leave it!

[LambtonParticipant @lambton]

I think ME issue 4470 is excellent.

The adverts are all at the front or the back of the collection of article (with one single page exception – Mytimemedia).

The contents and publication data are all on the first page seen when opening the magazine,

There is a very good selection of articles with something to suit most people. The mathematical formulas and chemical equations are only present in the two technical articles to make them scientifically complete. The reader does not have to fully understand or use them in order to gain some understanding of the topics. Please don't be put off reading the articles just because they look complicated.

The obituary of Dr Jonathan Minns I found very interesting and informative about a champion of our hobby whom will be greatly missed.

All round a very good issue of this magazine and I only wish that MEW was half as good.

Well done Diane and your team.

I found the article on 'Locomotive springing, adhesion and pulling power' very interesting Diane and it's not something I can recall being covered in such straightforward terms elsewhere before.

Although I model in Gauge 3 (the largest scenic gauge) and I've therefore not the quite the same 'traction' issues as those who passenger haul, I will still look at this article again when I come to re-spring my GNR Atlantic (as I will do shortly as part of its refurb). I have always used the same strength springs on all axles up to now….

The other pages of "Math" were regards to combustion – and although the formulae were way beyond what I can now remember of my calculus, there were none the less some very interesting points made about the nature of combustion that will inform me in the future. The math didn't detract from this info (and I'm sure some were happy to see the 'proof' ). I am quite capable of skimming over these parts to get to the grist (which I will admit I had to then re-read to let the salient points sink in – brain cells are getting lazy these days).

So actually – I thought these two "Maths" articles were some of the most interesting and thought provoking I've seen for a little while.

[Diane CarneyModerator @dianecarney30678]

Thank you Ian. I tend to agree. It does no harm to include something that requires a little concentration to understand. It's all about balance, isn't it? Too much of this and you would just put it down as being too much to take in but when there is a worthwhile subject to be covered… why not?

I have, in stock, another example of just such an article to do with calculations applicable to boiler design. My predecessor refused to publish it, dismissing it as uninteresting as it is purely mathematical but I think it will be coming up in the new year. It will not be everyone's cup of tea – I appreciate that – but to many it will be of great interest, whether or not they are intending to design a boiler. What are readers' thoughts?

Diane

[John BaguleyParticipant @johnbaguley78655]

I would be interested in the boiler design article. I also found the article on Locomotive Springing to be of interest and will use the calculations in the future.

Diane,

Go for it; I doubt I'll ever design a boiler, but it will be interesting to see how it is done. After all the magazine is called Model Engineer.

John,
And I would say do not exagerate you have never said that to me before. and I think you should get off your desk chair and get back into your workshop and business.
Oh ps.Diane apologies for spelling your name wrong was thinking of an old 60s record.

regards to all
Bob

[WearyParticipant @weary]

I too would like to read the 'Calculations Applicable to Boiler Design' article.

I am also one of the readers who found the 'Locomotive Springing, Adhesion and Pulling Power' article interesting – if in some parts a little challenging – but I survived!

[Geoff TheasbyParticipant @geofftheasby]

I found the article on combustion very interesting. I am intrigued that whole books have been written about it. I have one question. The author assumes that the Nitrogen in the air passes through the combustion process unaffected. 5N2 in equals 5N2 out. Is this just for propane or other similar gases, because in a car engine, which may run on such gases, you get Nitrogen oxides out as well. This is why modern cars have complex fuel injection and catalytic converters. I know petrol and diesel are more complex chemical mixtures than just propane, and that emissions are reduced if you use LPG, but they are still there.

I realise that these matters may have been omitted for simplicity, but perhaps it should have been acknowledged?

[Sub MandrelParticipant @submandrel]

Hi Geoff,

The amounts of nitrogen & sulphur compounds are negligible in terms of the thermodynamics, although they make measurable contributions to gross pollution – mainly because they are much nastier than CO2. One curious fact I remember from chemistry classes many years ago is that the calorific content of hydrocarbon fuels is almost identical, regardless of the actual composition.

Edit: LPG is virtually sulphur free, produces less soot (PM10s) and only 80% of the CO2 of petrol/diesel.

I too would like to say congratulations to Diane and your team for an excellent ME 4470.

I found the two technical articles to be most interesting and informative. After all, that is why I buy Model Engineer, to learn something! Any information that helps me become better at model engineering is most welcome on my part.

Regarding the article on boiler design; Like many others, I never expect to design a boiler, but would be most interested in reading that and other future technical articles. Definitely the way to go!

Regards

David
