We're expected to cover a wide variety of fields for a given project, including mechanical power transmission, electrical circuit protection, servo driven motion control, hydraulics, pneumatics, magnetics, lubrication, optics, and chemical compatibility. That's a pretty diverse list. The term "engineer" is used as a catchall, but it doesn't convey the broad list of tasks and fields we must cover to solve that problem.
What are we, then? We're the multi-talented, multi-skilled tool used to solve problems -- society's Swiss Army knife.
Oh, there may be some tasks needing a larger blade than that found on a Swiss Army knife. Some of us are highly specialized. Some focus on one or two aspects of the problem to be solved. One way or the other, we're going to cut right to the heart of the problem.
Even though National Engineers Week has passed, get the word out -- tell people what sort of knife you are.
