A weight can be hung in any of the following four ways by string of same type. In which case is the string most likely to break?

Answer:

Solution:

For a weight $W$ hung by two strings each making angle $θ$ with the vertical: $2 T cos θ = W \Rightarrow T = \frac{W}{2 cos θ}$ .

$T$ is largest for the largest $θ$ . In case (C) the strings are nearly horizontal, so $θ$ is largest and the string is most likely to break.
