DefinitionTerm
A change of cross section, such as an undercut, groove, hole or
shoulder. A notch leads to higher stress in the part. The flux of the
stress is interrupted or redirected.
notch
A force that is concentrated on a point.point force
A summary term for all forces and moments, thus loads and stress,
which act on a part.
strength
Force or pressure on a part. Stress is the force per unit area.stress
Safety to the stress beyond which the material exhibits permanent
deformation.

Calculating Shafts
With AutoCAD Mechanical, you can perform a shaft calculation using a
contour created with the Shaft Generator, or any other symmetric shaft
contour. The function provides a static calculation, which is important for
the design of the shaft and the bearing load.
In this tutorial, you calculate a gearbox shaft. The general way to calculate an
existing shaft is to define the contour and insert forces and supports. The
routine calculates all necessary values and draws the respective graphs for
moment and deflection.
Mechanical structure does not impact this engineering structure routine. You
can calculate shafts with mechanical structure enabled or disabled.
