The present paper attacks the problem of the modelling of a buoyant cable in a streamflow. The original idea was suggested by a very unusual problem: the design of a mobile art application consisting of a cable oscillating in the Tiber river. The underlying engineering problem is to estimate if and how such an effect would be possible. Precisely quantitative answers to the following questions should be produced: (i) what is the driving power needed to generate the desired large oscillations of the cable in the streamflow, (ii) what is the maximum forces at the cable head, (iii) what is the expected shape of the cable and at what frequency the driving motors should work to obtain the desired scenic effect.

Abstract
The present paper attacks the problem of the modelling of a buoyant cable in a streamflow. The original idea was suggested by a very unusual problem: the design of a mobile art application consisting of a cable oscillating in the Tiber river. The underlying engineering problem is to estimate if and how such an effect would be possible. Precisely quantitative answers to the following questions should be produced: (i) what is the driving power needed to generate the desired large oscillations of the cable in the streamflow, (ii) what is the maximum forces at the cable head, (iii) what is the expected shape of the cable and at what frequency the driving motors should work to obtain the desired scenic effect.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
