1. The problem statement, all variables and given/known data I have this question. I need to know the diformation in P direction. Here is the question I use the symmetry and finally with a 1/4 modell I get the following: which is correct according to the instruction. K is the stiffness of the spring. which with symmetry becomes k/2 and also P now I have this deformation according to my knowledge If I apply the formulas for beam deformation which I am allowed to do(in basic level) I got this: you see that deformation d1 in my third picture will have two componentes and it will not solve the problem. becouse : you see that i get problem writing f1x and f1z.. Can anybody tell me how to sett the solustion? f1x is the force in node 1 at x direction and so on. f2x will be p/2 cos45 and f2z will be -p/2sin45 and M2 2. Relevant equations 3. The attempt at a solution What I wrote up there.
