Equilibrium based Questions: Practice Problem & Solution

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? Equilibrium based Questions diagram: A flexible chain of weight W hangs between
(W. cosec θ) / 2
(W. sec θ) / 2
W. cos θ
(W. sin θ) / 2

Solution Explained:

To solve this problem, we apply the core principles of Equilibrium based Questions. Understanding the underlying formula is key to arriving at the correct answer below:

For Equilibrium in vertical direction

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