Ideal electrical systems (just idle curiosity)

Which is relevant to Mr Paste's post *how* precisely? Do tell, I'm keen to know.

[John Rumm]

Careful, the numpties will insist on a on you passing a mowing test first...

Wrong again Harry. It was a bit of blue-sky thinking about how it could have developed if it hadn't developed in the way it actually did.

[harryagain]

Drivel. It was posted as factual.

[Nightjar]

That only demonstrates that you didn't understand either the posting or the basis for the whole thread.

[John Williamson]

Pretty much par for the course with harry.

[Nightjar]

Seems worse lately though. Don't think he is a spring chicken so it may be Dementia creeping in. Despite his irrational postings and opinions I wouldn't actually wish that on him.

Indeed, I know a number of people whose lives have been affected by people suffering from it. It's not nice.

[Nightjar]

I'm not sure about 'creeping in'. Would anybody who was entirely rational have done what he did to his bungalow?

Nor on anybody.

[Nightjar]

Wasn't somebody who lived under one of the super grid lines done a few years back for stealing electricity by induction?

And how many only receive a shock some years?

Understand the sentiment but ...

The past two or three days someone nearby has been using a ride-on every evening and leaving some kids to career round the back roads for what seems like hours. Bloody noisy things they can be. And highly illegal for two boys of, I guess, around 10 to 12, to drive themselves on the public highway, sharing the single seat and almost falling off.

I have been waiting to see if Darwin will take a hand in this...

Anyway, ride-ons are very much out of favour at present.

With the "H&S won't allow that" attitude, some things stand out as notably dangerous, yet they seem to be allowed to continue ...

This week I noticed a council workman using a largish, walk-behind mower on about a 10' high bank angled steeper than 45°, looked like an accident waiting to happen.

[Tim Streater]

Not with me they're not.

And I think my mower must have access to this ng. Next time I went to use it after posting the above, the handle of mine snapped at the point where it joins to the body of the machine, leaving me with a lawn partly mowed. Luckily there is a bracket on the arm and on the body so I was able to splint it, roping them together and finishing the job.

The part is called an "arm lower" p/n 107-3887-03 and it snapped at the weakest point.

[Nightjar]

... or some other body part.

[polygonum]

I put my foot in it there...:-)

I would have thought that enclosing a cable in water would change the relative permeability of the arrangement, and hence the inductance per metre of the cable?

(too long since I played with transmission line theory!)

[Tim Watts]

I guess it might - I was considering the capacitative effects only.

But assuming the armour is steel wire - how much I wonder?
