I am trying to calculate the internal forces and their nature in this truss, however, I cannot seem to do so as both the method of joint and the method of section do not work. I think this is because there are not enough conditions of equilibrium that can be used. Is there any way to actually calculate the forces in the members even if this is the case?
For example, at joint A, there are 3 unknown members, and all the members acting through it are only concurrent at that specific point, making it impossible for me to use the equilibrium condition of the sum of moments being 0.
It would be extremely appreciated if someone could inform me about how to calculate the forces in the members of this truss. Thank you.
