The object accelerating downward exerts less force on the part below than if it were being held in place, But this is a reflexive situation: the lower section exerts less retarding force on the descending object - Newton's 3rd law. If the retarding force were greater, the object would have less...

I Know that an object accelerating downward exerts less force on the part below than if it were being held in place, But how does this relate to the top section of the WTC...
