The Chemistry of Polymer Molecules
14.1 On the basis of the structures presented in this chapter, sketch repeat unit structures for the following
Principles of Fracture Mechanics
8.1 What is the magnitude of the maximum stress that exists at the tip of an internal crack having a radius
of curvature of 1.9 104 mm (7.5 106 in.) and a crack length of 3.8 102 mm (1.5
The Kinetics of Phase Transformations

The two characteristics of component io
IMPERFECTIONS IN SOLIDS
Vacancies and Self-Interstitials
4.1 The equilibrium fraction of lattice sites that are vacant in silver (Ag) at 700C is 2 106. Calculate
the number of vacancies (per meter cubed) at 700C. Assume a densi
MECHANICAL PROPERTIES OF METALS
Concepts of Stress and Strain
6.1 Using mechanics-of-materials principles (i.e., equations of mechanical equilibrium applied to a freebody diagram), derive Equations 6.4a and 6.4b.
16.1 The mechanical properties of cobalt may be improved by incorporating fine particles of tungsten
carbide (WC). Given that the moduli of elasticity of these materials are, respectively,
9.1 Consider the sugarwater phase diagram of Figure 9.1.
(a) How much sugar will dissolve in 1000 g of water at 80C (176F)?
(b) If the saturated liquid solution in part (a) is cooled to 20C (68
ATOMIC STRUCTURE AND INTERATOMIC BONDING
Electrons in Atoms
2.1 Cite the difference between atomic mass and atomic weight.
Atomic mass is the mass of an individual atom, whereas atomic weight is th
5.1 Briefly explain the difference between self-diffusion and interdiffusion.
Self-diffusion is atomic migration in pure metals-i.e., when all atoms exchanging positions are of the same
