Long story. Following a lengthy conference call with engineers in NJ, two other engineers and I were tasked with finding certain parts in a Konex box, determine the part's material, and measure the angle between a bracket and a pipe nipple welded to it on one of the parts. We opened the two Konex boxes and ripped open enough of a wooden crate located in one of them to locate and extract the required parts.

The two other engineers with me, both PE's (hang my head in shame), started asking themselves if either one had access to an inclinometer to determine the angle. Me, I measured the perpendicular distance between the end of the pipe and the top surface of the bracket (3-3/4 inches) and measured the length of the pipe nipple that was above the bracket (4 inches).

They asked me what I was going to do with those dimension.

I replied "I am and Engineer and I know Trig!" I grabbed my cell phone, on which I have a scientific calculator application, and calculated the arc-cosine of (3.75 divided by 4). They thought I would have to Google the answer. My cell phone calculator said 20 degrees (within my measurement accuracy using a thin pocket tape measure).

The opposite angle is the one we really needed, so 90-20 = 70 degrees. 70 degrees matched what was shown on the fabrication drawings dating from 1981. Designs confirmed!

They were embarrassingly dumb-founded.

The material was 304 stainless. No old school math needed for this one as a number of the pieces contained the printed mill markings indicating 304SS.

I wish that I had my circular pocket slide-rule with me this afternoon. That would have been priceless!
