Who can give a detailed explanation? 
Toughness and strength are two properties that are often used interchangeably, but they actually refer to different characteristics of a material. Toughness is a measure of a material's ability to resist fracture, while strength is a measure of a material's ability to withstand stress without breaking.
Toughness and strength are related in that a material with high strength will generally also have high toughness. This is because a material with high strength is better able to withstand stress, making it less likely to fracture and thus increasing its toughness.
The importance of toughness and strength depends on the specific application. For materials that are expected to undergo a lot of stress, such as in engineering or construction, strength may be more important. However, for materials that need to withstand impacts or sudden changes in temperature, toughness may be more crucial.
Toughness is typically measured using a test called the Charpy impact test, which measures the energy absorbed by a material when it is struck by a pendulum. Strength, on the other hand, can be measured using a variety of tests, such as tension, compression, or shear tests.
Yes, a material can possess both toughness and strength. In fact, many materials have a combination of both properties, with some being stronger but less tough, and others being tougher but less strong. It is important to consider both qualities when selecting a material for a specific application.
