Why do circuit breakers go up for on and down for off?

Or the upper limit of the acceptable torque on the dial before you broke it and got no emergency service at all.

It was fun to try to dial a number by using a switch to make pulses.

You have enough money because you haven't spent half of it on insurance premiums. Remember folks, insurance companies make a profit. Keep that profit to yourselves.

Deliberately making something harder so the idiots can't use it and the good guys have to make more effort is entirely illogical.

Read again more carefully. Typically each house is provided 240V from one of the three distribution phases, and the distribution transformer (12kv or 21kv -> 240v) is center tapped to provide the neutral.

The neutral is tied to ground at the residence service entrance using copper ground rods (two bonded rods are required in my service area).

That's because they have several (usually four) bolts or nuts that are usually recessed - used to be behind hub caps.

Wire wheels on sports cars are fitted onto a spline and secured with a large "nut thing" with wings that you hit with a soft headed mallet; they could easily come loose if they rub against a mud bank if the threads didn't have the right chirality.

The smaller one would have to be big enough for the purpose so the bigger one would be too big.

The regulator isn't attached to a pipe; it's attached to a substantial valve on the top of the cylinder.

Rolls-Royce used to use splined hubs, with a single hub-nut, but the nut had a spring-loaded section around the hole. When the section was pushed in, it could be screwed on and off, but when it spring out flush to the surface of the nut, it locked into the splines. They supplied a special hub-nut spanner that held it in when installing or removing it.

Commander Kinsey doesn't do 'thinking'.

I see you haven't a f****ng clue. Quadcopters have two clockwise motors and props and threads and two anti clockwise, anrranged diagonally opposite so that torque is evened out, broadly. To turn it you vary the power to one set of motors versus the other. Pitch and roll is done by differential thrust on adjacent pairs

Not uncommon in this group.

Even single-shaft helicopters use coaxial counter-rotating main rotors.

My mother told me about that, using the phone's hookswitch. Its a way to make calls when you weren't supposed to and the dial had been disabled or removed. I seem to remember doing that once.

Recently, we have been getting a lot of ads for utility line insurance. Same thing, pay for repairs you may not need and pay more.

I remember seeing a drawing of a man standing in the smoking remains of a house and saying "at least I saved 68 cents on a new fuse".

I don't think anything I said contradicts your description. Two clockwise propellers run clockwise, to diagonally opposite anti-clockwise propellers run anti-clockwise. What you don't do is run a propeller two wrong way, otherwise you will generate "anti-lift" - a downwards force that acts in the same direction as the weight. I suppose very brief "anti-lift" on some propellers will change the attitude (left/right and fore/aft) more quickly than just stopping two props.

But a clockwise prop turning clockwise and an anti-clockwise prop turning anti-clockwise will generate identical lift, for the same speed, diameter and pitch angle. There's nothing that makes one direction better than the other, which is what Carlos's "actually they do" seems to imply. Just as right-handed and left-handed screws are equally good at joining pieces of wood/metal as long as you remember to turn them in opposite directions ;-)

I get one for electric or water lines every couple of weeks. Sure, it can happen but I've been a homeowner for 56 years and never had an issue that would be covered. This house is 4 years old so I'm not concerned. Better that money in my pocket. .

Not everything in the house. It was all over the attic, and in truth, I'm not positive it was still connected. I should ask my friend about that too.

Ah. A lof of safety enforcement is done by insurance companies that is not covered by government regulation. Is that true in Spain and Europe too?

I use the numpad even to type a 4 digit number. So much faster, easier, and more accurate.

That involved other people.
