Centroid and Centre of Gravity
Centroid Center of Gravity
• It is defined as a point about
which the entire line, area or
volume is assumed to be
concentrated.
• It is related to distribution of
length, area and volume.
• It is defined as a point about
which the entire weight of the
body is assumed to be
concentrated.
• Center of mass.
• It is related to distribution of
mass.

Center of Gravity
Consider system of n particles fixed within a region of space.
The weights of the particles can be replaced by a single (equivalent)
resultant weight having defined point G of application
