Web•Therefore Symmetrical breaking current = r.m.s value of a.c component = x / [2] 1/2 •Asymmetrical breaking current = r.m.s value of a.c component =[[x / [2] 1/2 ]^ 2 + y^ 2 ] •Breaking capacity is expressed in MVA by taking into account the rated breaking current and rated service voltage. Thus if I is the rated breaking current in amperes WebOct 12, 2015 · You need to factor a “safety factor” into your calculations. I use working stress, not ultimate strength. Usually shear governs for short spans, and bending … footed china mugs

And if we plug that into our calculator, we get that the pH after we add that hydroxide is 5.06. So it's a little bit higher. It went up by .06. That makes sense. We do imagine it ... footed coffee mugs
