Thank you for the video

[@eamonnquinn9585]

good and clear tutorial on this topic - Thank you

Glad to hear that it was helpful! Appreciate your feedback!

Very good video for basic understanging. Sir, can you suggest good book for reference for learning Stack up analysis?

Hello Sir
At 8:54 you have taken square root of SD (A Tolerance) + SD (B Tolerance)
At 9:07 you are again calculating Square root of Previous Answer + Square root of (C Tolerance)

[@instituteofqualityandrelia7902]

Hello Karti, thank you for your interest. For every dimension, you need to add variance. If all tolerances are assumed to have equal Cp, then you can add squared tolerances and take square root.

Sir you have taken square root two times Square root od A AND b Tolerance again calculating square root of c + previous answer
i have calculated square root of sd of a tolerance + sd of b tolerance + sd of c tolerance
Please check
Nominal Tolerance SD=Tol/6
A 25 0.5 0.083333333
B 10 0.2 0.033333333
A+B 35
C 35.25 0.2 0.033333333
GAP=C-(A+B) 0.25 0.9 0.095742711

Thank you. Apologize for the late reply. All the variances ( and tolerances) are perpendicular to each other. So we need to take square root again.

Sir, please remove the flickering of the letters.

Hello professor, appreciate your feedback. I will take a note of it and avoid it in future videos. RUclips doesn't allow changes in current videos.
