Planar lamina
In mathematics, a planar lamina is a closed set in a plane of mass and surface density such that:
The center of mass of the lamina is at the point
where moment of the entire lamina about the y-axis and moment of the entire lamina about the x-axis.
Example 1.
Find the center of mass of a lamina with edges given by the lines and where the density is given as.
center of mass is at the point
Planar laminas can be used to determine moments of inertia, or center of mass.
