Across
  1. 2. when springs are relieved of their stresses through heat treatment
  2. 5. gradual chemical or electrochemical attack by atmosphere, moisture or other elements on metals
  3. 6. suddenly applied loads
  4. 9. the property in extension springs not exhibited by any other spring because it’s an internal force wound into the coils during coiling
  5. 10. when the opening is less than one wire size
  6. 12. the adhesive strength of the grains in a metal, and their reaction (internal force) to an external force
  7. 15. includes threaded inserts, extended loops, hooks, machine loops, and crossover loops
Down
  1. 1. also known as resonance, occurs, when an extension spring is suddenly extended and stays in the extended position
  2. 2. include critical dimensional and load requirements
  3. 3. lifespan of a product
  4. 4. the process that is performed on the ends of springs after they are heat treated
  5. 7. the process of manufacturing different springs based on specifications
  6. 8. when the opening is greater than one wire size
  7. 11. the twisting action in torsion spring which produce rotation
  8. 13. a resilient device, typically a helical metal coil, that can be pressed or pulled but that returns to its form shape when released
  9. 14. occurs when a compression spring is loaded beyond its elastic limit causing permanent distortion
