Ea. Washington | Don't see anybody talking about a safety factor. My Ag engineering prof at college 60 + years ago always stressed a 100% safety factor. IE figure what will do the job and then double it for safety factor. Of course he didn't know anything about "just in time" manufacturing or any of the modern least cost engineering skills of today but always said " a little more iron is better then costly or deadly failure". Always worked for me. Good discussion. | |
