Sommario
Viene riproposto il problema della stabilità elastica di una trave uniforme a sbalzo su una fondazione generalizzata, sottoposta ad una forza di tipo “follower”.
Si indicano i valori dei carichi critici per differenti valori del coefficiente di tangenza e delle costanti della fondazione.
Summary
The problem of the elastic stability of a uniform contilevered beam on an elastic elements connected by shear layers and subjected to a follower force, is there reopened.
The critical loads for several values of the tangency coefficient and modulus of the foundation are shown.
