After completing today's reading, exercises, and the associated homework you should be able to:
Define the terms
thermal strain and
coefficient of thermal expansion
Distinguish between thermal and mechanical strain and know what strain to use in
Hooke's Law.
Find unknown forces, strains, stresses, and/or displacements for bodies subject to
multiple axial loads, including cases where multiple materials are present
Determine when an axially loaded static system is statically indeterminate
Solve for unknown forces, stresses, strains, displacements, etc. for static systems by
using equilibrium and
using Hooke's Law (the stress/strain relation)
looking at the geometry of deformation/geometric constraints, and
looking at the geometry of deformation/geometric constraints when thermal
effects are present
Identify a number of things that can cause a part to fail
Define and calculate a factor of safety (FOS)
Use a factor of safety in calculations
Note: Any term in bold is a key vocabulary term that you should be able to define, regardless of whether or not that is the specific learning objective.
