tensile bars

Tensile bars are standardized metal or plastic samples used in laboratory tests to measure how materials respond to pulling forces. They are typically shaped like a uniform, elongated rectangle or cylinder. When subjected to stretching, scientists measure characteristics such as strength, ductility, and elasticity. These tests help determine how a material will perform under real-world tension, informing engineering and construction decisions. The results provide essential data for ensuring safety, durability, and appropriate usage of materials in various applications.
