Here is a question for the gear heads out there from a gEEk:
I recently had a brainstorm for a great new consumer product. One of the components is a round tube roughly 24" long x 1" dia made of steel. As an engineer I dutifully sought out and applied the beam bending equation. I was able to find online calculators that gave me quick answers. Then I dutifully did a test. The calculators were wrong. Way wrong!!! I did them manually. The calculations were wrong, but matched the online calculators. I consulted a gear head. He said I'm using the equations correctly.
SOOO, here's the question. Why are the equations wrong? Test it yourself. Not even close.
"Work the problem from the beginning until you get stuck. Then work backwards from the answer. In the middle, lick and rub."
