Question

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 $\theta$. What is the tension of the chain at the endpoint?

Answer 1

See the free body diagram with the tensions at one

end ($T_1$) and at the center of the chain ($T_2$).

Balance the forces to get the answer.

$T_2$ = $T_1$ * Cose$\theta$

$T_1$ = $\frac{M}{2}$ * g * Sin$\theta$

So $T_2=\frac{Mg}{2}\ast Cote\theta$.
