This reminds me of a question a Mechanical Engineer asked me way back when I worked for Elscent, an Israeli company, on theIR Translate/Rotate CAT Scanner Its design was such that to collect the data for an image it would first slide the X-Ray Tube on one side of the patent with the detector assembly on the other side. When it finished the transition it would rotate the whole gantry 72 degrees, and then slide the other way. It would do this 5 times to complete the data collection, and then re cock itself to it start position. The motion was hydraulic driving and the data collection as well as the motion control was all electronics.
Elcent used to assign both an Electronic (me) and Mechanical Engineer to service each of their CAT Scanners in operation. I worked a few years with a young Jew Mechanical Engineer from Haifa. Alas his name has escaped me some time back, but not the question he asked, “How do you tell an Mechanical from an Electronic Engineer in the bathroom?” “I am not sure” I answered. “Well”, he said, “The Electronic Engineer goes ahead and does his business, and then washes his hands, while the Mechanical Engineer washes his hand and then does his business.”
