Note: There are some modules that do not like self-intersecting lines, e. These become 0 if one uses the modulus-weighted centroid as the origin (Note: like finding center of gravity but use E rather than ρ) If one uses the modulus-weighted centroid as the origin, the equations reduce to: FF F EfA T TOT + == 11 * − + = − =+ MM M EfI fI zz T z TOT zyz 12 3 ** − + = − =+ MM M EfI fI yy T y TOT yz y 12 3. It is not a problem when you are calculating centroids because when you divide two values this factor will cancel itself, but if you use it for anything else you will get wrong results. The demographic problem is one of the most important and problematic. We calculate the average pressure at the centroid. The centroid is the location that we can model the shape as if the entire weight acts through this point. Hence there are at most two centroids, and the cost is at most n/2. Repeat steps 2 and 3 until the centroids don’t change. We will approach harder problems later. For two dimensional problems (constant thickness) it su ces to specify the xand ycoordinates, x = R xdA R dA y = R ydA. So if you have 300 frames, x_centroids is an array of 300 x centroids.
