A pendulum bob of mass $m$ is released from rest at horizontal position A. At which position is its string most likely to break?

Answer:

Solution:

Let $ϕ$ be the angle from downward vertical.

$v^{2} = 2 g ℓ cos ϕ$ .

$T = \frac{m v ^{2}}{ℓ} + m g cos ϕ = 3 m g cos ϕ$ .

Tension is largest at bottom D.
