I have this question for MSE:

Coiled springs ought to be very strong and stiff. Si3N4 is a strong, stiff material. Would you select this material for a spring? Explain.

I looked up this material, and I found that it's very strong and stiff, and i figure it WOULD be good for springs, but when I researched it more, I realized that springs are rarely made of it and it's more often as plates, part bodies, screws, etc.

So does that mean it's not good for springs? Thats what I assume, but I don't see why not. Please help?

It seems I think that the traditional way of adding numbers from right to left is kinda like using pliers for all the bolts.

Is there a way to add numbers from left to right?
We write numbers out left to right and say them also.

School? shows/teaches the basic method of adding columns working from right to left.

Which is mind torturing trying to remember the numbers to say them back to you if your doing the problem in your head.

Care to sample? Add your phone number to itself and then say the answer. Its a lot of numbers to remember and its hard to do.

Is there another way? Adding numbers from left to right?

1. if an object travels for 15 min with a constant velocity of 12 miles per hour west ,what is the acceleration?

2.A sportcar goes from a velocity of 12 meters per second east in 2 seconds. what is the cars acceleration?

3. A train takes a long time to stop. thats what makes trains so dangerous to people who cross the tracks when one is near. if a train is traveling at 30 miles per hour south and takes 12 minutes to come to a stop what is the trains acceleration?

I have most of the equation written out I just want to make sure I am getting it all down.

Humans have been releasing EMI radiation into space for 106 years. That's over 623 trillion miles traveled. A light-year is equal to about 5,878,625,373,183.61 statute miles. The first radio broadcast was Dec.23 1900 by Reginald Fessenden. Over 500 stars are within this range.

In those glue bottles, not gluesticks, how does all that sticky liquid glue NOT stick to the inside, if it sticks everything else together? I choose best answers rather quickly, so the faster you answer, the better of a best answer chance. ^^

Heh, weird question, I know, but I noticed that when I was shaving my legs, and it is also on my arms. :P And I'm wondering if it is because one side of my body gets more blood than the other or something. :P
