The capstan equation or belt friction equation, also known as Euler-Eytelwein formula (after Leonhard Euler and Johann Albert Eytelwein), relates the hold-force to the load-force if a flexible line is wound around a cylinder (a bollard, a winch or a capstan).It also applies for fractions of one turn as occur with rope drives or band brakes.

Capstan equation - Wikipedia Jump to content From Wikipedia, the free encyclopedia Formula relating load-force and hold-force on a line wound around a cylinder A flexible line wrapped around a cylinder that is subject to a holding tension can achieve a greater loading tension due to the effect of friction. Schematic of quantities for capstan equation An example of holding capstans and a powered capstan used to raise sails on a tall ship. The capstan equation [ 1 ] or belt friction equation , also known as the Euler - Eytelwein formula [ 2 ] [ 3 ] describes the tension required to cause slippag
