Hai again. I'm irritated at a question and I'm not entirely sure how the conversion thing goes. I've got the numbers right but I don't got the numbers in the right places... See below: It's from a book called Engineering Studies The Definitive Guide. Q. Find the resistance of a copper wire...

Thanks. Wasn't sure if they could've just half the diameter instead of making it more complicated. But now I know a new (probably redudant) equation and that some maths here will try and be tricky. I'll be sure to ask again when I'm bewildered.

On the Excel Senior High School Engineering Studies (author by Peter M & Roger M) text book page 28, where I'm introduced to the Engineering Mechanics and Hydraulics, there's an example where the area is divided by 4. I'll rewrite the work: Tensile stress Determine the Ultimate Tensile Stress...
