Document Summary
Suggested additional reading: sections 1. 1 to 1. 15, and 2. 1 to 2. 5, 2. 9, 2. 10, 2. 12, 3. 8 in textbook. 3. 3. 3 distribution of stress in a body (differential equations of equilibrium) 3-13. 3. 3. 4 2d stresses acting at a point and stress transformation 3-18. 3. 3. 6 3d stress state and transformation at a point 3-28. 3. 3. 8 3d principal stresses and mohr"s circle 3-37. 3. 3. 9 solving for 3d stresses using eigenvalues and vectors 3-46. 3. 5 stress strain relationship: hooke"s law 3-82. 3. 7. 2 determining applied loads from strain gauge measurements3-109. The larger objective is to and relate the stress and strain to the applied load. This will be critical when determining if a structure is safe when we will look at failure criteria in a following chapter. In this chapter the concepts of forces and stresses reviewed in chapter 1 and the material concepts of chapter 2 are used to determine stress and relate stress to strain, respectively.
