Tensile strength tests measure how much force a material can withstand while being stretched or pulled before it breaks. This test is crucial for understanding the durability and performance of materials like metals, plastics, and composites. During the test, a sample is placed in a machine that gradually applies tension until it fails, allowing engineers to determine its maximum tensile strength. The results from tensile strength tests help in selecting the right materials for various applications, ensuring safety and reliability. Industries such as construction, automotive, and aerospace rely on these tests to evaluate materials like steel, aluminum, and polymer composites for their specific needs.
