Etymology

Origin of bending moment

First recorded in 1855–60

Example Sentences

There’s another way her shoe could break, and this is due to the compressive stress due to the bending moment applied to her heel every time she walks.

From Forbes

This moment is called the “bending moment” at the section, it is the product of the load W and the distance of the section from the loaded end, so that it varies uniformly along the length of the beam.

From Project Gutenberg

As regards the strain in the beam, the longitudinal and lateral extensions and contractions depend on the bending moment in the same way as in the simpler problem; but, the bending moment being variable, the anticlastic curvature produced is also variable.

From Project Gutenberg

The deflection of the beam is determined from the equation curvature of central line = bending moment � flexural rigidity, and the special conditions at the supported end; there is no alteration of this statement on account of the shears.

From Project Gutenberg

The second noteworthy result is that the curvature of the strained central-line is not proportional to the bending moment.
