One measures tensile strength of a material. What is the difference between that and tensile modulus? One measures flexural strength. What is the difference between that and flexural modulus? Tell me the difference in measurements and physical significances.

I assume it would be ok to get fired since engineers get laid off all the time for no reason, but a friend says it can destroy their professional image. What do you think?

What is the most amperage you can pull through each circuit? The dimmers they attach to are 2.4K but I've heard you can only pull 14.6 amps per circuit. It is multi-cable with 6 circuits per cable.

I work in utility construction. Many times we have to remove bolts and/or nuts that are rusted - "frozen tight!" - even after we spray them with various penetrating oils to "loosen them up."

How does this work? I put a wrench on the nut/bolt, pull as hard as I can. Nothing happens. Then I put a 5 ft. long pipe on the end of the wrench, pull on the end of the pipe (opposite side from wrench), and my "pulling" is 1/2 as hard, and the bolt/nut unscrews!!??

Sure, I understand this is called "leverage," but that does not make me understand WHY, with the pipe, I pull 1/2 as hard! I mean, the bolt/nut will STILL require more 'pull' than my arm can give, to 'break free,' but with the pipe, I see to "get-more-pull", with 1/2 the required strength.

This does not make sense. I guess I am saying, if you use a air wrench to tighten up the nut with 100 pounds of pressure, to remove it again -should require 100 pounds of pressure. My arm is pulling 50 pounds of pressure, so nothng happens!

I am working on a robot with a club; one of our best ideas involves using tank like tracks instead of normal wheels. We don't want to waist a huge amount of money on these but we want descent quality. Does anyone have any idea where we could purchase these?

I'm supposed to do a report on the Cone Penetration Test, but I am having a little trouble. What does it mean when it says the CPT is a "versatile sounding method (used to determine the materials in a soil profile and estimate their engineering properties)"?? What is "versatile sounding" ???

thank you, sorry if this should be obvious and isn't to me. Thanks!!!!
