Retaining walls: FS against sliding

[@BestCheckedIn]

You were my favorite teacher at SDSU!

[@ericb5457]

sometimes a soil to footing coefficient is given, sometimes it needs to be solved

[@picajoool]

I have never, ever seen that someone uses coefficient of 1 for friction?! Usualy 0,666 or 0,7 for soil to concrete interface.
Can you give name of the book that says your value of 1?

[@mohammedrafi5487]

Is it 467

[@mohammedrafi5487]

202.5?
