    neutral currents

    three phase is a little more difficult to explain in terms of water as above but I'll give it a go.. There are 3 "circulating pumps" The neutral is a bucket At any given time 1 pump is filling the bucket while the other two are emptying it at a slower rate.. In a balanced load, the amount...

    God does not exist - discuss

    "I walked down the road the other day and saw a man with long greasy dreadlocks down to the middle of his back.. I therefore put it to you that barbers don't exist..... because if they did exist then no one would have long messy hair......" without suffering and pain we wouldn't know the...

    What tool/method to use to hold washer in place

    or it could be a riv-nut in the frame that is lose and just turns with the bolt.. if you can "wedge" a screwdriver into the gap between the two parts of te frame ( ie the fixed bit and the arm that swings ) then that will apply pressure on the bolt and whatever it's screwed into and may hold...

    Cutting box section how best to do it.

    just to be clear, these are metal cutting DISK's not blades?? ( ie a grit like material not metal with teeth? ) you can get metal cutting blades for chop saws and circular saws so use one of those.. it's unlikely that the hole dimension of the cutting disk would match that of your saw and...

    dispute over shared chimney stack. any advice please?

    The problem with that party wall act is that it is YOU that wants the repairs done, not him.. So he has the right to get a surveyor and make YOU pay for it. He has to agree to the costs etc before YOU can proceed with the repairs.

    Coljack?

    never ever miss breakfast.. always eat something within half an hour of getting up, just choose sensibly.. if you read a cerial packet the nutritional value is usually for about 30g of cerial with milk.. which is not as much as you think it is.. it really is just about sensible healthy...

    Coljack?

    slight exageration on the van bit though.. it was my own van and wasn't re-inforced.. It was an escort van and it failed an MOT for rust and I tried to buy a new one, but they changed the design a it and moved the bulkhead behind the driver forward a bit so the seat didn't go back enough for...

    gate latch - making it more secure?

    the simplest solution would be to drill a hole through the latch to the right of the nut / bolt that it pivots on, and through the plate behind. a single padlock then goes through the hole so that you can't lift the latch... ie

    Extractor Fan for Bathroom

    depends entirely on the fan.. if you get one that is on a humidistat then you just wire the transformer ( located away from the shower, usually by the door ) to the live side of the lights ( via a 3 pole fan isolator ) if you want it to come on with the lights then you wire the transformer...

    box section or I beam? ( and other questions ).

    ah yes, reading it back now I can see I wasn't very clear.. I should have said side by side and I meant 3 beams running in parellel, not in a H configuration ( which from your post I take it is how you read it?) I'm designing ( or rather re-creating a site I once worked on ) some flats /...

    box section or I beam? ( and other questions ).

    Thanks for the help so far.. I did say it's theoretical :D , and the number of beams and boxes shouldn't make a difference to the general theory, it's the joint between any 2 boxes over the one beam that I was trying to describe.. failing that, the containers are self supporting when...

    box section or I beam? ( and other questions ).

    I could, but I really want ( in my head at least ) to have the beams extend past the containers and form a "balcony" at either end.. hence wanting to run them front to back.. like this..

    box section or I beam? ( and other questions ).

    before I start I'd like to preface the following by saying that this is just theoretical / for fun in my head and not an actual project or anything.. can you put a "join" in a load, on top of an I beam? what I mean is imagine you have 2 shipping containers, say, and want to run beams...

    Hands or brain ?

    yes but without the knowledge of dentistry / anatomy (human and animal) etc, the money wouldn't be there... would you pay me the same rate as a surgeon to remove your gall bladder even if I was a concert pianist ( displaying a higher / similar level of manual dexterity but none of the knowledge )?
