In the context of centroids and moments, what do ##\bar{x}_{\textrm{el}}## and ##\bar{y}_{\textrm{el}}## represent?
For example:
$$\bar{x}L = \int \bar{x}_{\textrm{el}}dL$$
For example:
$$\bar{x}L = \int \bar{x}_{\textrm{el}}dL$$
Thanks for your response, mathman.I have no idea where this came from, so I can't go into any more detail.
xEL and yEL represent the location of the centroid of a tiny element of length dL or a tiny element of area dA used to calculate the first moments of length or area.In the context of centroids and moments, what do ##\bar{x}_{\textrm{el}}## and ##\bar{y}_{\textrm{el}}## represent?
