Oops. Sorry guys. Dave's right. I'll get calibrated after a while here. Have a great one.

Thanks, Al. Same to you and yours -- and everybody out there on ShopTalk....I guess I will believe you. I just don't understand. We ran out of tuition money in the middle of the 9th grade. Thanks.I know I often say that some effect is straightforward from freshman college physics. NOT THIS! Yes, someone might be able to derive it from physics 101 -- but I certainly didn't. I didn't see this phenomenon until a structural engineering course in my junior or senior year of E-school.
Yes, I understand it... And it's clear to me that John and Alan do, too. But please allow for the fact that we're engineers. As such, we have a need to explain and justify our points. That is when we tend to wander into things like cross-sectional moment of inertia, and the fact that compressive and tensile modulus of elasticity is the same in shaft materials. These seemingly gobbletygook terms actually have a meaning, and in fact actually explain the answer to your question. But they only explain it to another engineer.
Happy holidays!
