Buckling of columns

The column is described as a vertical member of the structure that carries an axial compressive load, and buckling is a lateral deformation of the column under the application of load.

Learning Goal:
To be able to solve three-dimensional equilibrium problems using
the equations of equilibrium.
Part A
As with two-dimensional problems, a free-body diagram is the first
step in solving three-dimensional equilibrium problems. For the
free-body diagram, it is important to identify the appropriate
reaction forces and couple moments that act in three dimensions.
At a support, a force arises when translation of the attached
member is restricted and a couple moment arises when rotation is
prevented.For a rigid body to be in equilibrium when subjected to
a force system, both the resultant force and the resultant couple
moment acting on the body must be zero. These two conditions
are expressed as
The J-shaped member shown in the figure(Figure 1) is supported by a cable DE and a single journal bearing with a square shaft at A. Determine the reaction forces
Ay and Az at support A required to keep the system in equilibrium. The cylinder has a weight WB = 6.00 lb , and F = 1.40 lb is a vertical force applied to the
member at C. The dimensions of the member are w = 1.50 ft , l = 6.00 ft , and h = 2.00 ft .
