A sign in our EMC Lab read:

"One experiment is worth a thousand opinions"

Anybody want to MEASURE the difference?

How about making a guy with a piece of philystran,
a long (10 ft) piece of EHS followed by a short  (4ft)
piece of EHS, using guy grips, and a turnbuckle.

Tension this between two solid supports and observe
the LOOS gauge reading on the short and long pieces
of EHS?
