Possibly, there again this will have the worst performance of any possible configuration except for flapping wings. People in the past have got into trouble for designing cruise missiles and the like (which is not very difficult if you are after minimum viable product performance), I think we...
In which dik either demonstrates a complete misunderstanding of %ages, or knows damn well what he is doing and uses them to mislead (a politer version of what I initially wrote). See post 132. The %age is dropping slightly, the coal use is increasing, as Tugboat said. So which is it dik? Are you...
B&K produce an excellent series of manuals and technical notes on signal analysis in general and vibration monitoring. The HP/Agilent intro is also fine...
True but does not support your easily disproved claim. Their coal consumption is increasing. 95% of the coal power stations being built are Chinese. Here's the graphs for China
The Guardian spills the beans on new power stations in China (yes they are retiring a few as well)

I wonder why dik keeps pushing this lie. It is easily refuted. Here's what the AI thingo says
China is the world's largest coal consumer, using more than half of the global total. While coal consumption has been relatively stable in recent years due to slower economic growth and government...
It's cheap and easy apparently https://yle.fi/a/3-10736252 . No mention of the costs of storage or transmission lines.
You can do it in Kazaqkstan Transition towards a 100% RE-based energy system was modelled for five scenarios considering different energy system structures, from a limited...
"Another reference.. slightly different equation"
That word slightly is doing a LOT of work. Consider the case where mu=1 and alpha = 45 degrees. (this makes me think the - sign in the denominator is correct)
In South Australia's case (2016) they installed natural gas generators, and hospitals and the like added emergency generators. It also flushed out the errors in configuration of the software for the windfarms. Since then they've also built another interconnector back to the coal powered NEM as...
So I've got 5 spring/masses in series, dropped from 1m.
SDOF approximation using Gautam's equation
m1dof = 1.0103
k1dof = 3.9898e+08
freq1dof = 3162.8
h1dof = 1.0000
Force1dof = 8.8931e+04
max force at ground from 5dof model
ans = 9.7014e+04
So this ties up reasonably well with the FEA...
Well yes, in your dynamics textbook or lecture notes.
Here's a long article that manages to avoid using differential equations, but only because he uses FEA to derive the correct equivalent mass.

In a success story for the transition to Net Zero, on April 16 Spain's grid was 100% renewable for a full day. In a rather large step backwards the grid collapsed across large parts of the Iberian peninsula and even into France, on the 28th.
I suspect they'll blame the software like the...
Not helped by a generation of journalists that 'write' articles by cutting and pasting press releases. I wrote to one pointing out various errors in her story and she responded 'but that's what the press release said'. That was in the Business section which you might hope had a bit of an...
3 is a very big spherical cow. And no, that is a very horrible approximation, you've assumed it behaves like a point mass on a spring the real issue is that it is a continuous system.
Two propellers in series will not be very efficient, although I suppose if you increase the pitch of the second it might help. Putting a 2 bladed prop into a tube turns it into a ducted fan of sorts.
Conceptually think of the bar as a series of springs and masses. As the mass hits the ground the spring above it compresses, and so on and so forth up the chain of springs and masses.
As you can see there's a series of compression and rarefaction waves set up in the system.
It looks like it...
"It used to be the case that large EPC contracts would be bid at cost or even below and the contractor would make his profit on the variations and additional work." One company I worked for had this down to an art form. Bid at almost zero profit, then encourage the customer to upgrade the design...
Every marginal kWh of electricity used is generated by fossil fuel. I was wrong above, coal is not in the absolute majority, but fossil fuels are, and continue to supply 60-70% of electricity.
