graphic demonstration of Saint coming

[reye]

Good morning to all,
My professor of construction science spoke of a graphical demonstration of de Saint Venant's postulate regarding the situation in which it is considered to discharge the lateral surface. do you know where I can find material on this topic?
Thank you.

I would say that the material is recoverable to the same professor who said it.
apart from the jokes, there's a little problem... a professor of science who claims he wants to demonstrate a postulate, that is, an axiom, must have breakfast with the cognac :biggrin:

Cit. "We must demonstrate that the state of tension on the Saint Venant solid is multiaxial(?). demonstration can be done both graphically and analytically. we take a section of the beam and induce a tetrahedron of cauchy. our goal is to look for an exhaust plan. we take an areola and assume that it acts a tau in any direction. I put naked (?) and it is noted that the tau on the cut section is not there and therefore I found a plan in which sigma x, sigma y and tau xy are equal to zero". What do you think?

by section cut your prof by chance means that "stacca" just a piece and what is found in the hand is obviously unloaded as it is detached from the rest of the body on which the force acts?:tongue::biggrin:

joke!

I honestly can't understand what your teacher wants!

Oh, okay, it's not de Saint Venant's postulate. I consider the postulate what it says that on a body the local effect of forces extends for a portion of the solid of the same size as the whole of forces.

what you say you can prove.. .to remember how...

Do you know where I could find material about it? it would be important for me to understand the demonstration
