- Homework Statement
- find the deformation of the structure and find delta(N).

- Relevant Equations
- deformations equations

Hi, i'm struggling with that problem , i need to find the distance that point N went down.My way of thinking is that the structure is twice not statically determined because of the beam MN and beacuse of the left support which is also unnecessary in order for equilibrium. My 2 equations of deformation in order to find the variables are d(N)-d(M)=d(Lmn) and d(N) of the left beam equal to the d(N) of the right beam.

i thought to denote the force of the beam as N and then to divide to to each beam (pic 1) then i got the problem that i have a beam with no support and a force that causing it do go down, so i tought (pic 2 ) that the beam NM is equal to support there and got the problem that if there is a support it wont get down. in addition to that i cant figure out if the force that bending one beam is causing the torsion of the other , because the left doesnt resist that its only has a translational resistance. I wonder if my initial analysis is somehow correct and what other perspective there is to solve problems like this. thank you.
