Horizontal beams are structural elements that run parallel to the ground. They are commonly used in construction to support loads, such as roofs or floors, by distributing weight evenly across their length. These beams can be made from various materials, including wood, steel, or concrete, depending on the requirements of the building. In engineering, horizontal beams play a crucial role in maintaining the stability of structures. They are often part of frameworks, such as trusses or frames, and help resist bending and shear forces. Proper design and placement of horizontal beams are essential for ensuring the safety and durability of a building.
