Engineering - April 2007

It would seem less trouble to make and take up less storage space if they were made with straight sides.

Three registers on my max demand meter read as follows: Max dem 1 = 13.81kw.
Max dem 2 = 10.86kw. Max dem 3 = 2.92 kvar. These settings do not alter - albeit my max demand meter has never been re-set. What do these settings mean and are these figures used to multiply average usage.

Since I've had this meter installed my consumption in kwh has increased by three times my previous historical kwh usage.

Ok, so I've decided next year to do a project, but I'll need an accelerometer. Some qualifications include:
1. Has to be able to withstand a considerable amount of g's.
2. Has to be able to withstand a considerable amount of impact.
3. Has to not be affected by position (basically, if turned upside down it wont go all wacky).

Considering that both delta and grounded wye have the same line to line voltage, would the insulation level be the same for both delta and grounded wye to protect from ground faults?

You know in movies they show someone singing so high that the glass breaks, or windows shatter. At what frequency does a typical wine glass break at?

I have a standard in writing in front of me, but I don't know where it comes from. The standard is stated as "Escape ladders must also be provided from service levels so that no point on a platform is horizontally more than 75 ft in walking distance from a main or secondary exit. An Engineer that I am working with believes this to be an OSHA standard, but I have not been able to find it on their site. I suspect it may be a NFPA standard, but you need a paid subscription to search their site. If someone does know this to be OSHA, do you know which code number it is?

I ask this because I had owned a bicycle that I used on a daily basis. I stored it outside part of the day while at classes on campus, and then stored it inside my apartment at night. Both my front wheel bearing and my rear wheel bearing failed (the shafts would get loose inside the outer cylinder).

Now, this was an el-cheapo Huffy bicycle with crappy parts, but will heating/cooling bearings reduce the lifetime further? It seems to make sense to me that expansion/contraction could be stressful, but I want to be sure.

I hope that my newer, much better quality, bike will not suffer this problem.

As opposed to using a purely one-phase system, why do we use primarily three-phase systems throughout the world? Also, why not use more than three phases?

I ask this since I am a TA for a power systems/energy conversion laboratory course, and I want to give my students a good list. I have several reasons already, but I want to make sure I haven't missed anything.

So, list away! And thanks in advance for the help.
