Q: A structure is made from identical, axially compressible robs connected to a rigid foundation. The rods cannot buckle. In the unloaded configuration the angle between the rods and the horizontal is (alpha); then angle becomes (1-Beta)*alpha when p =/= 0. Find the relationship P(Beta). Introduce a suitable non-dimensional load P and make a plot of P vs (beta) the region of -0.5 < Beta < 2.5.
My attempt:
I thought og using the Total potential energy approach, TPE = SE - Work done... but i have no idea how to get started on it. There is another method called the equilibrium method that my tutor talked about but i can't make any sense of how to start it.. Any help will be much appreciated.
