A
k = Tt * ke * T
2
Q
Beam elements
A
displacements in x and y (forces), and also rotation in z in each extremal point (moments).
1 beam element: 6 degrees of freedom.
3
Q
Types of stiffness
A
longitudinal stiffness (EA)/L , bending stiffness (EJz) / L^3
4
Q
Simple axle model
A
Summation of forces in x in y and in z. With this you get the result for the simple axle model.
