A flexible chain of weight W hangs between two fixed points A and B at the same level. The inclination of the chain with the horizontal at the two points of support is θ. What is the tension of the chain at the endpoint? Image related to
(W. cosec θ) / 2
(W. sec θ) / 2
W. cos θ
(W. sin θ) / 2

Solution:

For Equilibrium in vertical direction

2T  sin θ = W ⇒ T = W/(2 sin θ) = (W cosec θ) / 2
