    Why Coulomb's Wedge Theory Ignores Earth Pressure at Rest

    Hi! Can someone tell me why Coulomb in his Wedge Theory of Earth Pessure didn't take into considertion Earth pressure at rest? He cosnidered only limit active and passive pressures, but why didn't he write anything about pressure at rest? I 've looked up some books, but there is only the...

    What Does It Mean When Longitudinal Stiffness (EA) Equals Infinity?

    So when the longitudianal stiffness is equal to infinity, we don't have to calculate the displacement due to the normal forces, but when longitudinal stiffness has some finite value, than the normal forces cause displacement and we can calculate, f. ex. by Maxwell Mohr formula. Thank you both...

    What Does It Mean When Longitudinal Stiffness (EA) Equals Infinity?

    Homework Statement Can somebody please explain me: What does it mean that Longitudinal Stiffness (EA) is equal to infinity? What does it change if for some members of a structure "EA = infinity", and for other members "EA = finite number". Homework Equations I know that we use longitudinal...

    Finding equation for regression curve

    use some software as Mathlab or Mathcad, find the algorythm for 'Polynomial Approxiamtion' and you will obtain approximating polynomial for given data (x and y values)
