Unformatted text preview: location of the centroid. 12/4/10 Centroids & Center of Mass/Gravity Center of gravity vs. Center of mass The point at which the resultant weight of a system of particles acts. Since c.g. depends on the acceleration of gravity, center of mass is a better term to use. Center of gravity of the solar system??? Center of mass is independent of gravity. 12/4/10 c.g. ∑ ∑ ∑ ∑ ∑ ∑ = = = W zW z W yW y W xW x Center of mass ∑ ∑ ∑ ∑ ∑ ∑ = = = m zm z m ym y m xm x 100 lb 300 lb 100 lb (4,8)f t (10,6)f t (5,3)f t Find the center of gravity....
