I googled this while trying to figure out a homework problem, and thought your voice sounded familiar. Thank you for the video and your podcast, Materialism.

Thanks so much for sharing this! I'm a Brazil engineering student and this video helps a lot!

[@TaylorSparks]

Glad to help!

thanks, I checked your sample just before quiz.

What if we have the yield strength and we need to find sigma node?

[@user-mq6gl4ui1d]

When gives more numbers for yield stress and d …. What use from values when compute constant hall pitch equation?????

So glad to help! Who knew Hall Petch could be mortal ;)

Sabiendo que la resistencia del titanio es 450Mpa cuando su tamaño de grano es 17 * 10-6 m y su resistencia es de 565,4Mpa cuando su tamaño de grano es de 0,8 * 10- 6 m. Calcula

No hay q usar hall petch para eso. Hay q usar matthiessens rule.
