Irony is when a video from 2012 helps you more than your useless college. Thanks a lot.

This is how uncertainty propagates in an 'absolute tolerance system', rather than a 'statistical tolerance system'.

Professor, thank you for great explain, would you give a brief calculation for propagation of error for multistage

is this error propagation?

There's something missing (for me) in this explanation. That is, how is the uncertainty, characterized? Most elementary treatments of this topic treat uncertainty a random and normally distributed variable. In that case, you would not use these formulas.

No reasoning is given for considering the uncertainty as +/- 0.7 cm for the case of the half = 10 cm. The +/- 0.7 cm is not intuitive, and seems lacking logic. There is something behind which is not said. What about working on 1 cm, or even 0.1 cm, instead of 20 cm, will its uncertainty be considered in both cases as +/- 0.7 cm. Is "adding" uncertainty to become +/- 0.7 cm logic?. Where is the "general role" that everybody may apply? This adds "ambiguity" to the whole issue rather than removing it as assumed. No one can accept uncertainty of +/- 0.7 cm on a piece of 1 cm in length , for not to talk about the uncertainty of +/- 0.7 cm on a piece of 0.1 cm in length, otherwise we are in a world of "science fiction" rather than in a real "physical world". Roles, whatever they are, cannot drop the "simple intuitive logic". What does "this uncertainty" mean after all this strange story?

Width and height? These are not the width and the height, these are the length and the width of the wood plate.
