O.K., Thanks, I get it now. The bottom of the panel is one of the small (2ft2) sides. BTW, the superscript for ft2 was dropped during editing of the original article, so the areas are shown as ft instead of ft2.
I'm confused. In the example shown, there are three (3) dimentions for the panel area (2ftx4ftx1ft), but this should yield a volume (ft3), not ft2, as shown in the example. Assuming a rectangular prism with six (6) sides, there are two sides with 8ft2 each,two with 4ft2 each, and two with 2ft2 each, for a total surface area of 28ft2. Also, which side is the bottom surface that you are ignoring? Did I miss something? Please help.
Using wireless chips and accessories, engineers can now extract data from the unlikeliest of places -- pumps, motors, bridges, conveyors, refineries, cooling towers, parking garages, down-hole drills and just about anything else that can benefit from monitoring.
With strong marketplace demand for qualified engineers across the board that currently outstrips the available supply, there may never be a better time for engineers and project managers to advance their careers and salaries. Whether those moves are successful in the short-term and long-term is likely to depend on how the transition from one job to the next is handled.
