A moment can be anywhere from a few seconds, up to a minute. Generally, a moment is defined as a point in time lasting from 1-3 seconds.
In Old English, a moment was an exact measurement of time being 1.5 seconds or 1/40th of one minute. However, in more modern English usage it has simply meant an inexact and brief length of time.

Well. I have heard 2 answers, both are similar.
The first was that a Moment is a medieval measurement of time being 1/40 of an hour, or 90 seconds, (1.5 Minutes).
But the second one was that it is 1/40 of a minute or 1.5 seconds.
Both seem reasonable but I also heard that it has to do with an angular measurement.
Perhaps it is the amount of time it takes for the earth to rotate x number of degrees?.
The relation between bending moment and the second moment of area of the cross-section and the stress at a distance y from the neutral axis is stress=bending moment * y / moment of inertia of the beam cross-section
define moment of inertia§ I is the moment of inertia of the mass about the center of rotation. The moment of inertia is the measure of resistance to torque applied on a spinning object (i.e. the higher the moment of inertia, the slower it will spin after being applied a given force).
it occur where moment becomes zero in bending moment diagram.
The internal moment that tends to want a beam to bend around the center axis
MAXIMUM SHEAR force bending moment is zero shear force change inside is called bending moment
