At the end of this section you should be able to:

1. Identify relevant material properties for axial properties and find them on a table

2. Solve for deformations and stress in problems with purely axial loading for

   • Statically-determinate problems

   • Statically-indeterminate problems

   • Problems with a change in temperature

3. Estimate maximum stress in object with abrupt geometry change using stress concentrator equation and plots

Axial Deformation and Stress focuses on how axial loading produces normal stress and change in length in bars, rods, and columns. You will identify the material properties needed for axial deformation (such as elastic modulus and thermal expansion data), then solve axial stress and deformation for statically determinate members and for statically indeterminate members using equilibrium plus compatibility, including composite members in series and in parallel. You will also analyze thermal loading and temperature change effects, gap and constraint problems, and estimate peak stress near abrupt geometry changes using stress concentration factors and standard charts for features such as holes and fillets, with Mathematica resources provided for efficient equation solving and checking.
