On a smooth pulley of radius R hangs a homogeneous flexible rope of mass / length $λ$ and length $ℓ$ (Fig.). Find the maximum tension in the rope.

Answer:

Solution:

$T_{m a x} - T_{0} = λ g R [1 - cos θ]$

$T_{m a x} = λ g R + λ g (\frac{ℓ}{2} - \frac{π R}{2})$

$= λ g [\frac{ℓ}{2} - (\frac{π}{2} - 1) R]$
