Explanation:

The given statement states that "The following bracket is welded to the vertical column. The joint undergoes torsional stresses." We are asked to determine if this statement is true or false.

Torsional stresses:
Torsional stress is a type of stress that occurs when a material is subjected to a twisting or torsional force. In the case of a welded joint, torsional stresses can be generated due to applied torsional loads.

Welded joint:
A welded joint is a type of joint that is created by joining two or more pieces of metal together through the process of welding. Welding involves melting the materials at the joint and allowing them to solidify, creating a strong and permanent bond.

Torsional stresses in welded joints:
When a welded joint is subjected to torsional stresses, the twisting force applied to the joint causes the material to deform. This deformation can result in the development of shear stresses within the joint.

Analysis of the given statement:
The given statement states that the bracket is welded to the vertical column and undergoes torsional stresses. To determine the correctness of this statement, we need to consider the following:

1. Geometry of the joint: The geometry of the joint, including the shape and dimensions of the bracket and the column, will determine how the torsional stresses are distributed within the joint.

2. Applied forces: The magnitude and direction of the applied torsional forces will also affect the development of torsional stresses in the joint.

3. Material properties: The properties of the materials used for the bracket and the column, such as their strength and stiffness, will influence how they respond to the applied torsional stresses.

If the bracket is sufficiently designed to handle torsional loads and the welding process is carried out properly, then the statement may be true. However, if the bracket is not capable of withstanding torsional stresses or if the welding is not done correctly, then the statement may be false.

Conclusion:
Based on the given information, it is not possible to determine the correctness of the statement without further details about the geometry, applied forces, and material properties. Therefore, the correct answer is option 'B' - False.
