That's not how errors add up, it's nonlinear. You have to take the sum of squares. So in your case, it wouldn't be 10 * 0.01 = 0.1, but sqrt(10 * 0.01^2) = 0.03

- privatelypublic 1y agoI provided a "worst case", not statistical, example. For those who want an example, calculator, and demo see: https://www.smlease.com/entries/tolerance/tolerance-stackup-analysis/ https://www.smlease.com/entries/tolerance/tolerance-stackup-... NB: using disks like the site does provides a clearer example.
