An Instructive Eye-Bar Test
A. C. Cunningham · Transactions of the American Society of Civil Engineers · 1894
From a lot of nine steel eye-bars one was to be selected for test. The bars were apparently perfect with the exception of one, and in this bar one of the finished heads contained three seams. It was decided to take this bar for testing, as the seams condemned it for use, and in the event of failure on account of the seams, it could be reheaded and retested.
