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.

Question

Q.2) An exerciser shown in Figure 2 begins with his arm in the
relaxed vertical position OA, at which the elastic band is unstretched.
He then rotates his arm to the horizontal position OB. The elastic
modulus of the band is k 150 N/m that is, 150 N of force is required
to stretch the band each additional meter of elongation. Determine the
moment about 0 of the force which the band exerts on the hand B.
