Figure 3.1 Vorlex-excited strumming vibrations of a taut marine cable. The solid lines denote the predicted strumming 

 response and the individual points denote the displacements (A) and frequencies (•) measured by Dale, Menzel and 

 McCandless (45). Cable length, L — 0.9 m; cable diameter, D = 2.5 mm. The frequencies of the three natural cable modes 

 are noted on the left-hand vertical axis.
