Question

Help answer this question below.

I've seen guys welding on top of buildings being built when it was about 5 F / -15 C degrees outside. Wouldn't the steel be contracted when it's that cold, and put stress on the welds when it warms up?

    Newton's Law states that atoms move very very fast until they are hit by an apple.
