  1. Stress
    Force / area ⇒ σ = P/A
  2. Strain
    ΔL/L
  3. Displacement (axial load)
    δ = PL/AE

    where E = Young's Modulus
  4. Types of Loads
    • 1) External
    • 2) Internal
    • 3) Reaction
  5. Location of Centroid


  6. Saint-Veriant's Principle
    For a column with a load applied; after traveling away from the load for a distance equal to the column width, the stress distribution is approximately uniform. (Equal to the average stress)
  7. Stress at a Point
    σ(x,y,z) =
  8. α (alpha) =
    Thermal Expansion Coefficient
  9. Thermal Strain
    εth = αΔT
  10. Thermal Displacement
    δ = αLΔT
