1. Explain why tensile testing is an important current practice, although most of the mechanical properties of standard materials are available in literature and databases.
2. Define the material's strength and toughness. What is the difference between these two material properties?
3. Describe the effect of temperature on the material properties. Give an example of a material that is affected by temperature and describe how it is affected
4. Describe the correlation between material properties and possible/feasible manufacturing processes. Give an example to support your answer.

I want you to answer every question correctly with explanation so simple that even a kid will understand.
