Angle section
Channel section
Box type section
Any of the above
Answer is Right!
Answer is Wrong!
The correct answer is: C. Box type section
A box section is a type of structural steel section that is made up of four plates that are welded together to form a rectangular or square shape. Box sections are very strong in both bending and torsion, which makes them ideal for use in places where these forces are present.
Angle sections and channel sections are also strong in bending, but they are not as strong in torsion as box sections. Therefore, they are not the best choice for use in places where torsion occurs.
The following is a brief explanation of each option:
- Angle section: An angle section is a type of structural steel section that is made up of two plates that are welded together to form an L-shape. Angle sections are strong in bending, but they are not as strong in torsion as box sections.
- Channel section: A channel section is a type of structural steel section that is made up of two plates that are welded together to form a C-shape. Channel sections are strong in bending, but they are not as strong in torsion as box sections.
- Box type section: A box section is a type of structural steel section that is made up of four plates that are welded together to form a rectangular or square shape. Box sections are very strong in both bending and torsion, which makes them ideal for use in places where these forces are present.
