He pulled out a grimy napkin and wrote:
"Your software," Ramon said, tapping Singer's Chapter 14 (Columns), "assumes a perfect world. It used Euler's formula for long columns. But this is a short, square column. Euler doesn't apply here." Strength Of Materials By Ferdinand Singer 3rd Edition
He flipped the pages to the section on and the Secant Formula . He pulled out a grimy napkin and wrote:
This is a unique request. Since "Strength of Materials" by Ferdinand Singer (3rd Edition) is a classic engineering textbook filled with formulas (stress, strain, torsion, beams, and columns), a "good story" related to it would need to personify these concepts. Euler doesn't apply here
The architect froze. He had assumed pinned ends. Ramon, by looking at the rust pattern at the base, saw a fixed end.
He stood before the column. It was a reinforced concrete rectangular strut, 400mm x 400mm. He didn't look at the crack. He looked at the buckling .
