What type of beam has a hollow square or rectangular cross section?

  1. Channel

  2. Hollow

  3. Box

  4. Lattice

The correct answer is: Box

A beam with a hollow square or rectangular cross section is known as a box beam. Box beams are designed with a closed shape, which gives them structural advantages, such as improved resistance to bending and torsion compared to solid beams. This hollow construction allows for a lighter beam while maintaining significant strength and rigidity, making them suitable for a variety of applications in construction and mechanical systems. The uniformity of their cross-section aids in distributing stresses evenly, enhancing their load-carrying capabilities. Box beams are commonly used in applications such as bridge construction, frameworks, and support structures where both strength and weight efficiency are crucial.
