Testing process (Seen above, the C shaped construct and the reference key locking a spring in place for testing with the Z010 Zwick/Roell (Ulm, Germany) upon initiation the C shaped will be shifted up and down so that each end delivers forces onto the spring which are then recorded by torque device (Sauter DB 0.5-4, Grindelwald, Switzerland) this process is repeated five times total in both directions for every spring tested)
