Rubber sheet dynamics

Problem posting article due to equations

FYI, I'm having trouble uploading a .pdf document with a technical article.  Posthaven appears to be having difficulties rendering the equations in the article.  I'll try another method and re-post.

I think it is a display issue on Posthaven.  The file can still be downloaded accurately.  I've also uploaded it to my ASU Google Drive and created a link to it inside the post.
