Calculate the member diagrams for the point load P for the pinned beam at two ends.
From the equilibrium of forces we calculate the reactions F1,F2,F3.
We make a section 0<x<L/2 and calculate the internal forces.
We make a section L/2 <x<L and calculate the internal forces.
Diagrams for Axial Force, Shear Force and Moment are following.
Based on Figure 1, we get: where:...
The rod of the picture is loaded with the force 2...
