Title: Combined Uncertainty vs Adding Uncertainties
Post by: fruitypebbles210 on September 25, 2020, 09:49:27 PM
When do you use the equation of combined uncertainties and when do you simply add uncertainties? Example, if we're dealing with two tolerance measurements of two glassware, do I use the equation for combined uncertainty (square root of squared sums) or simply add this together?
