Professor in your video at 15:37 timing I'm worried about 2 in the equation. The 2 should be outside under root as per me, and if not can you please explain as to why is the 2 under the root in equation tb >= (2 * stress/ phi * fy)^0.5 * c Thanks a lot in advance for the answer and Thanks for making this video.
great RICHARD
Thank you 😊

Great video! :)

What's Phi and Zpl how it equals area
Unable to understand Moment of resistance formula .What is Phi and
Zpl
Phi is a partial material factor. It's the inverse of gamma used in the Eurocode. Zpl is the plastic section modulus, called Wpl in the Eurocode.
@@richard_walls Material safety factor means partial safety factor 1.15
@@vvats_chauhan the partial factor we use is 0.9. we multiply it by the material yield strength.
