Frictional losses during one cycle of bending of a multi-strand cable with
one end free and the other clamped are considered. A quasi-static approach is used
which is based on the assumption that inertia forces affect neither the contact pressure
between the strands nor the coefficient of friction. Expressions defining
boundaries of slipping sections and angles of slippages are derived. The overall
frictional losses in the cable are found by integration over all the slipping sections.
It is shown that the deflection of a cantilever cable is smaller when an
internal friction is taken into consideration. A simple formula for the lost displacement
is given in the case of high internal friction.
