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.
I teach an introduction to engineering seminar to grade 6 students and I tell them that engineers are "the ones who take science and make it affordable". The sample is a pencil that has 8 pieces and with parts costs, assembly, shipping, handling, etc., it sells for less than 10 cents - AND - the store selling it and everyone in between made a profit! That's engineering.
Iterative design — the cycle of prototyping, testing, analyzing, and refining a product — existed long before additive manufacturing, but it has never been as efficient and approachable as it is today with 3D printing.
People usually think of a time constant as the time it takes a first order system to change 63% of the way to the steady state value in response to a step change in the input -- it’s basically a measure of the responsiveness of the system. This is true, but in reality, time constants are often not constant. They can change just like system gains change as the environment or the geometry of the system changes.
At its core, sound is a relatively simple natural phenomenon caused by pressure pulsations or vibrations propagating through various mediums in the world around us. Studies have shown that the complete absence of sound can drive a person insane, causing them to experience hallucinations. Likewise, loud and overwhelming sound can have the same effect. This especially holds true in manufacturing and plant environments where loud noises are the norm.
The tech industry is no stranger to crowdsourcing funding for new projects, and the team at element14 are no strangers to crowdsourcing ideas for new projects through its design competitions. But what about crowdsourcing new components?
It has been common wisdom of late that anything you needed to manufacture could be made more cost-effectively on foreign shores. Following World War II, the label “Made in Japan” was as ubiquitous as is the “Made in China” version today and often had very similar -- not always positive -- connotations. Along the way, Korea, Indonesia, Malaysia, and other Pacific-rim nations have each had their turn at being the preferred low-cost alternative to manufacturing here in the US.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
