Answer the following Review questions for each chapter. Depending on your book, these questions are either found at the end of the chapter or at the end of the book.

2.3 What is the difference between primary and secondary  bonding in the structure of materials?

2.8 Define the difference between elastic and plastic deformation in terms of the effect on the crystal lattice structure

2.9 Identify some materials that have a crystalline structure.

3.1 What are the three types of static stresses to which materials are subjected?

3.2 State Hooke’s law. 

3.3 Define tensile strength of a material.

3.4 Define yield strength of a material.

3.16 What is hardness, and how is it generally tested?

3.20 Define viscosity of a fluid.

4.1 Define density as a material property.

4.2 Theoretically, the melting point and freezing point of a  crystalline element, such as a metal, are the same temperature value, true or false?

4.3 When a solid metallic element is heated to its melting temperature, it requires a certain amount of heat energy to  transform to the liquid phase. What is the name of that  heat energy?

4.8 What is thermal conductivity as a material property?

4.10 In machining operations, coolant fluids are often used to  reduce cutting temperatures. What liquid material is  almost always used as the base for these coolants because  of its high heat-carrying capacity?

4.11 Name two manufacturing processes that depend on mass  diffusion.
