Can someone please cite a natural or man-made small scale real-world example of a progressive collapse?
The term "progressive collapse" seems to have come into vogue after 9/11 as a way of explaining how WTC 1, 2, & 7 collapsed. However, I have yet to see any natural or even man-made small scale examples of this phenomena. Can somebody please provide me with a real world example of a progressive collapse that can be reproduced in a laboratory on a small scale? More precisely, can someone show me how one object can gravitationally move through another object of equal or greater mass at or near free fall speed? Please try to avoid using the collapse of building structures such as WTC 1, 2, & 7 as examples.
Also, please consider the Law of Conservation of Momentum when providing your answer.
Thanks.
