Dptions

Part A $-$ Define the compatibility condition $k\frac{N}{m}$ Assume that the posts are nigilly connected to the beam and that the posts are subjected to the uniform, distributed load applied to the beam the top of the steel posts due to the axial force.

Learning Goal:

To determine the axial force in a statically indeterminate, axially loaded system and to learn about displacement compatibility

$F_B,F_a=kN,kN$
