Part B - Write the equilibrium equation
Construct the equilibrium equation (in terms of force) that relates the axial load in the steel and aluminum
posts to the distributed load applied to the beam. Let Fa and Fs equal the magnitudes of the force in
each of the aluminum and steel posts, respectively.

An infinitely rigid, weightless beam is supported by three circular posts, as shown. The outer posts are made of A-36 steel, and the central post is made of 2014-T6 aluminum. Prior to loading, all posts have a length of 250 mm. The system
is subjected to a distributed load of 200 kN/m. Assume that the posts are rigidly connected to the beam and that the posts are subjected to the uniform, distributed load applied to the beam.
Enter a compatibility condition that relates the displacement of the tops of the steel and aluminum posts due to the unknown axial forces in the posts. Let da be the displacement of the top of the aluminum post due to the
axial force and d be the displacement of the top of the steel posts due to the axial force.
