Question

A flexible chain of weight W hangs between two fixed points A & B which are at he same horizontal level. The inclination of the chain with the horizontal at both the points of support is θ . What is the tension of the chain at the end points?

TestHub · Accepted Answer

By symmetry each end exerts tension T at angle θ with the horizontal. Vertical equilibrium: 2 T sin θ = W . T = 2 sin θ W ​ = 2 W ​ cosec θ .
