Moments and Center of Mass of a Variable Density Planar Lamina Let be a continuous density function on the planar lamina R. The moments of mass with respect to the x and y axes are ∫ ∫ = R x dA y x y M ) , ( and ∫ ∫ = R y dA y x x M ) , ( . If m is the mass of the lamina, then the center of mass is ( 29 . , , = m M m M y x x y If R represents a simple plane region rather than a lamina, the point ( 29 y x , is called the centroid of the region....
