Behavior of the string considering axial elongation

open access: yesNihon Kikai Gakkai ronbunshu, 2016
A flexible string is used at various places. Typical examples are a cable for power transmission and communication and a wire for cranes and elevators. In addition, there are the uses such as a fly-fishing line, climbing rope and a mowing machine to cut ...
