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
