How does one apply EA on the downswing without tension and pushing? I can apply EA on the backswing by pulling on my left thumb wiht my right arm, however in transition and startdown, EA collapses becasue my arms are dropping. I guess I could maintain EA if I continue to push my right arm upwards as my pivot throws/swings the power package downplane.. Is that what is meant by a heavy sledgehammer like feeling?

Well...the same way.

Swing something (like a little steel washer or something) on a string and examine it. Why does it keep the string taught?

Weight rotating around a centre.
