Flexure refers to the bending or curving of a material or structure when subjected to an external force. This phenomenon is commonly observed in beams, bridges, and other engineering structures, where the material must withstand loads without breaking. The degree of flexure depends on the material properties, such as elasticity and strength, as well as the shape and size of the object. In engineering, flexure is an important consideration in design and analysis. Engineers use principles of mechanics to calculate how much a structure will bend under specific loads, ensuring safety and functionality. Understanding flexure helps in the development of durable structures like bridges and buildings, which must endure various forces throughout their lifespan.
