Hi,(adsbygoogle = window.adsbygoogle || []).push({});

This is not an homework. I'm doing a old exam question and have diffuclities. Since there is not a solution I want to get confirmed before I goes further with other similar question.

I have the figure belove.

The problem is here

I do like this. Since I should have some bending moment I insert a fictive bending moment which is made by the forceN. Then I do draw the forces in different part and solve the system. When I have N then I use the relation N = k.d where K is the stiffness coefficient of the spring. and then I solve for d. Forces R1 and R2 är equal since N is in the middle of the sctructure. But if I insert the fictive force They take other values right? or am I wrong?

I wonder if this is the right wat to do these kind of problem. Please guide me! thanks :)
