Lecture 13 Center of Gravity and Centroid 2. Composite Bodies A composite body consists of a series of connected simpler shaped bodies, which may be rectangular, triangular, semicircular, etc. Such a body can often be sectioned or divided into its composite parts and, provided the weight and location of the center of gravity of each of these parts are known, we can then eliminate the need for integration to determine the center of gravity for the entire body. The formula for calculating the coordinates of the center of gravity for composite bodies: Where:
EXAMPLE: Locate the centroid of the plate area shown in Fig. 917a.
