The application of bending stress in beams is extremely widespread in reality, for instance：
1.Bridge Design：
In bridge engineering, bending stress in beams is a core consideration. Engineers need to accurately calculate the bending stress of bridges under various loads to ensure their safety and stability. By designing the cross-sectional shape, size, and material of beams reasonably, the bending stress distribution can be optimized, improving the load-bearing capacity and service life of bridges.
2.Architectural Engineering：
In architectural design, the analysis of bending stress in beams is equally important. Whether it is a frame structure, shear wall structure, or other structural forms, beams play a crucial role in transmitting and distributing loads. By calculating the bending stress of beams, the overall stability and safety of the structure can be evaluated, providing a scientific basis for architectural design.
3.Aerospace Engineering：
In the aerospace industry, precision in structural design is paramount. The wings, fuselage, and other components of aircraft are subjected to complex loads during flight, with bending stress being a primary load form. Therefore, in aircraft design, the bending stress characteristics of beams must be fully considered. Through precise calculation and analysis, the safety and reliability of aircraft structures can be ensured.
4.Machinery Manufacturing：
In machinery manufacturing, bending stress in beams also plays a significant role. For example, in machine tools, cranes, and other equipment, beams are key load-bearing components. By calculating and analyzing the bending stress of beams, the design of equipment can be optimized, enhancing its load-bearing capacity and service life.
