How do heat treatment techniques like quenching and tempering contribute to enhancing the mechanical properties of materials in the field of mechanical engineering?

What is Toughness in Mechanics of Material?

Explain the mechanism of the corrosion fatigue and thermal fatigue, how to prevent/protect from your design?

Define the term Deformation of a body?

Why are pairs of materials more likely to experience thermal stress problems when they represent two different material classes?

the behaviour of  sponge material under stress

When does fatigue occur in metals?

You have been asked to obtain an object/structure/component that has failed (It may come fromyour home, workshop, an automobile repair shop, a machine shop, and so on) and investigate to:1. Determine the cause and type of failure (i.e., simple fracture, fatigue, creep).2. What are the working and environmental conditions that causes the failure?3. Propose measures that can be taken to prevent future incidents of this type of failure.4. After you have determined the failure type of your case study, your leader asked you to writeshortly about the other mechanisms of failures.

Consider the following data for a range of materials. In which of the following situations is creep likely to occur? Melting temperature of various materials: Melting Temperature (°C Material Ti alloy 1668 Carbon steel 1375 Alumina 2070 Nylon 66 polymer 262 A carbon steel component under continuous load in a power station operating at 200°C. A nylon pipe carrying fluid at 125K. All of the scenarios. A Ti alloy in a turbine operating at 350°C. An alumina ceramic component in a furnace operating at 600°C.

How can we apply the equations for plane-stress transformation, using a graphical procedure?
