Material strength refers to the ability of a material to withstand an applied force without failing or deforming. It is a crucial property in engineering and construction, as it determines how much load a material can bear before breaking. Common measures of material strength include tensile strength, compressive strength, and shear strength, each indicating how a material reacts under different types of stress. Different materials exhibit varying levels of strength. For example, steel is known for its high tensile strength, making it ideal for construction and manufacturing, while rubber has lower strength but offers flexibility. Understanding material strength helps engineers select the right materials for specific applications, ensuring safety and durability.
