Radiator construction

And not to betray my age but I was also required to sort out a Wheatstone Bridge in one of my core classes. Baffled me then and frankly I have never used it in thirty plus years in the field. Instructor was adamant that we understand it. He was maybe 90! Hah! I would love to throw a 4-20MA loop on him today! All that for a Mechanical guy! Never understood some of the rationale behind curriculum. I ended up helping establish curriculum for Mechatronix classes at a couple universities. I can assure you there was no Wheatstone bridges included!
Haven't heard that term for decades.
