The first moment of an area is defined as the integral of the (distance
from axis about which the moment is being calculated), where the
integration is carried out over the area. The second moment of an area,
also known as the moment of inertia, is defined as the integral of the
(distance from axis)^2 where the integration is carried out over the area.
I am familiar with the second moment of an area and its uses in mechanics,
however I am not familiar with the first moment.
Can someone refer me to a resource which explains the physical significance
of the first moment of an area and also for what calculations is this
property of an area used?
Thanks in advance for your help.
