Calculating Moments of
Inertia and Deflection
Lines
Many engineering calculations are automated in AutoCAD
®
Mechanical. This tutorial illustrates
how you calculate the moment of inertia for a profile section, and calculate the deflection
line on a beam based on the profile calculation.
Key Terms
DefinitionTerm
The moment of all forces that act on the member to the left of a
section (a point along the member where bending moment needs
to be calculated) taken about the horizontal axis of the section.
bending moment
A curve representing the vertical displacement of different points
along the member subjected to a load.
deflection line
A load or force that is exerted over a certain length.distributed load
A support that prevents translation as well as rotation about all
axes.
fixed support
Force or moment acting on a member or body.load
An important property of areas and solid bodies. Standard formu-
las are derived by multiplying elementary particles of area and
moment of inertia
mass by the squares of their distances from reference axes. Mo-
