Centroids and Moment of Inertia
for composite figures
Determine the centroids (x, ỹ) of the figure shown
below from the axes of reference (blue arrows)
Use the blue arrows as the axes of reference.
Take note that when the axis of reference is not at the end of the figure, the
left side / the downward side values must be negative using Varignon's
R20
Theorem.
Ex: in finding x from the set y-axis, the value of the centroids of individual
figures on the left is negative, while on the right side of the figure is positive.
