Homework Statement
differance between tensile and yield strength. please help.
Tensile strength refers to the maximum stress a material can withstand before breaking or fracturing. It is a measure of the material's ability to resist tension or pulling forces. On the other hand, yield strength is the maximum stress a material can withstand without permanently deforming or changing its shape. It is a measure of the material's ability to resist compression or bending forces.
Both tensile and yield strength are important factors in determining the strength of a metal. However, yield strength is more closely related to the material's ability to withstand real-world stresses and is often used to design and test materials for structural applications.
Tensile strength is measured by applying a gradually increasing tensile force to a material until it breaks. The maximum force applied is then divided by the cross-sectional area of the material to determine the tensile strength. Yield strength is measured by applying a gradually increasing compressive force to a material until it reaches a specific amount of deformation or strain.
Yes, it is possible for the tensile strength to be higher than the yield strength. This is because tensile strength measures the maximum stress a material can withstand before breaking, while yield strength measures the maximum stress a material can withstand before experiencing permanent deformation. In some cases, a material may be able to withstand a higher amount of stress before breaking than it can before permanently deforming.
Temperature and other environmental factors can have a significant impact on the tensile and yield strength of a metal. High temperatures can decrease both the tensile and yield strength of a material, while low temperatures can increase them. Additionally, exposure to corrosive environments can also weaken a metal's strength over time. It is important to consider these factors when selecting a material for a specific application.
