The graphs illustrate the force transmitted by a free-falling steel ball on a load cell Between the ball and the instrument there are 3 test pieces consisting alternatively of natural rubber, ethyl-vinylacetate (E.V.A.) and AN-VI. The test was performed under equal conditions (highness of the fall and size of the pieces): AN-VI absorbs the shock energy completely (there is no second or rebound shock) and this reduces the transmitted force.
