6.3 Incremental dynamic measurement

Replace the existing first sentence by the following:
This technique for measuring the incremental stiffness K (x ) according to Equation (3)

uses a superposition of a d.c. signal of certain magnitude (for example, constant restoring
generating a d.c. position x ) and a small a.c. signal (e.g. restoring force F ) as
