Abstract
The article considers the problem of determining the extra effort that occurs when the steel
weir rope winding on the drum and the bend on the blocks. Considered the steel weir rope element,
which goes from a straight section to the curved on the block. In this case there arise tensile force
(or compression force), which lead to the destruction of weirs of the steel weir rope. The proposed
new calculation, which is based on the classical theory, namely Hooke's law. A comparison of the
calculated values with the experimental ones.
