Flexural tests are used to measure the bending strength and stiffness of materials, particularly in construction and engineering. During the test, a sample is subjected to a load until it bends or breaks, allowing engineers to assess its performance under stress. Common materials tested include concrete, wood, and metals. The results from flexural tests help determine the material's ability to withstand forces without failing. This information is crucial for designing structures like beams and bridges, ensuring they can support expected loads while maintaining safety and durability.
