Gravity variation data observed in the process of seismogenesis and occurrences of earthquakes show that the location with the greatest gravity changes does not necessarily coincide with the epicenter. To explain this we defined the center of effective mass of stress volume as "hypocentroid", and ...
This method uses the center of gravity of the polygon; the geometric center of a feature. For line, polygon, or three-dimensional features, it is the center of mass (or center of gravity) and may fall inside the feature or outside the feature. For multipoint, polyline, or polygon featur...
Gravity variations in space and time associated with the model involve a tectonically stressed volume surrounding a small volume of an impending rupture (fault) zone. They refer to the center of effective mass of the total stress volume which is defined as `hypocentroid', the projection of ...
One factor affecting the stability of the Skywalk is the center of gravity of the structure. We are going to calculate the center of gravity of the Skywalk, and examine how the center of gravity changes when tourists walk out onto the observation platform. The observation platform is U-shape...

This chapter discusses centers of gravity and centroids. A solid body is made of a very large number of small bodies or particles; the earth attracts each one of these particles toward its center by the force of gravity. Each gravitational force is known as the weight of the particle. ...
