In the context of centroids and moments, what do ##\bar{x}_{\textrm{el}}## and ##\bar{y}_{\textrm{el}}## represent?

For example:

$$\bar{x}L = \int \bar{x}_{\textrm{el}}dL$$

The integral itself looks like a first moment, where the integrand is a function of position. 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.

Study pp. 1 and 2 of the link carefully. :wink:
