Most of you have used steel cooking pots, exposed to gas
flames, or even an open campfire.

Some of you have even tried oxy-acetylene or arc welding,
to heat up steel to its melting point.

So what do you observe when you heat up steel below its
melting point?

Does it explode violently, or does it simply behave like weak
flaccid rubber and start sagging?

Watch this video to help you decide:

Just remember: popular opinion is NOT always correct!

Hundreds of years ago, most Europeans and so-called
scientists believed that the Earth was flat, and that if you
sailed too far from land, your ship would fall off the edge of
the Earth. Even religious leaders castigated and outcast
anybody who claimed that the sun was not the centre of the
Universe.

narrated by Dr Judy Wood, PhD.

What should be internal diameter of a pipe to let 160L/second water flow vertically (at 75o angle water fall).

what would the degree of angle be for a 10% road gradient? would 5% be half the degrees? would 25% be 2.5x as much?

I claim a complete lack of expertise in this area, so don't hold it against me if I come up with some stupid ideas. I just wonder if there is a way to improve how we look for miners after a collapse.

What if miners began to wear powerful radio transmitters during these operations so that their precise location could be determined in three dimensions after a collapse? Perhaps their three-dimensional position could be cyclically broadcast via radio transmission. At the very least, the strength and source direction of a radio signal would hopefully offer information regarding the location of the miners.

Are these mines just too deep underground for such a thing to work? Then, might fiber-optic cables survive a mine collapse? Perhaps a device kept near the miners could keep track of its own location and transmit this information via cable...

If anyone has thoughts or ideas, speak out. There has to be a solution!

I need help trying to figure out this problem, 1000 ft of 18 gauge wire has a 6.385 resistance. How do you get A and D?

A 6 V source is connected to a 100 Ω resistor by two 12 ft lengths of 18 gauge copper wire. The total resistance is the resistance of both wires added to the 100 Ω resistor. Determine the following: (pg )

(a) Total resistance =

(b) Current = 59.9 mA

(c)Voltage drop across the 100 Ω resistor. = 5.99 V

(d)Voltage drop across each length of wire. = 4.61 mV

You only have one piece of paper (11 inches by 8 1/2 inches). No tape, staples, etc. It has to support itself. You can't support it on it ends (e.g. Have it tied to bigger pieces of paper.
