Resilience and its Definition
Resilience is a fundamental property of materials in mechanical engineering. It refers to the ability of a material to absorb energy when deformed and then release this energy when unloaded. It is an important characteristic to consider when designing and selecting materials for applications that involve cyclic loading or impact.
Explanation of the Correct Answer: Option 'A' (Elastically)
The correct answer to the given question is option 'A' - Elastically. When a material deforms elastically, it means that it is able to recover its original shape and size after the load is removed. Elastic deformation occurs when the applied stress is within the elastic limit of the material.
Resilience and Elastic Deformation
Elastic Deformation: When a material is subjected to a load, it undergoes deformation. In the elastic range, the material deforms elastically, meaning it can regain its original shape and size when the load is removed. This elastic deformation is reversible, and the material stores energy during this process.
Resilience and Energy Absorption
Energy Absorption: When a material is subjected to external forces, it absorbs energy in the form of strain or deformation. This energy absorption occurs during the elastic deformation of the material. The energy absorbed is stored in the material as potential energy, which is released when the load is removed.
Resilience and Energy Release
Energy Release: When the load is removed from the deformed material, the stored potential energy is released. This energy release causes the material to return to its original shape and size. The ability of the material to release energy is known as resilience.
Conclusion
In conclusion, resilience is the property of a material to absorb energy during elastic deformation and to release this energy when unloaded. Elastic deformation allows the material to recover its original shape and size, and during this process, energy is absorbed and stored. Resilience is an important characteristic to consider in material selection as it determines the material's ability to withstand cyclic loading or impact.
