Find the center of an irregular shape
Did you know?
WebIf a physical object has uniform density, then its center of mass is the same as the centroid of its shape. The requirement for the formula described above is 'a non-self-intersecting closed polygon', so the vertexes of the polygon will form only one non-self-intersecting closed polygon. The centroid of a uniformly dense planar lamina, such as in figure (a) below, may be determined experimentally by using a plumbline and a pin to find the collocated center of mass of a thin body of uniform density having the same shape. The body is held by the pin, inserted at a point, off the presumed centroid in such a way that it can freely rotate around the pin; the plumb line i…
