... Answer: The tension is zero. By the same v v2 v1 argument as in the question above, one can show that the acceleration is straight down when the mass on the extreme right with the string horizontal. Since the acceleration is straight down, the net force must be straight down, so there can be n ...

Hunting oscillation
Hunting oscillation is a self-oscillation, usually unwanted, about an equilibrium. The expression came into use in the 19th century and describes how a system ""hunts"" for equilibrium. The expression is used to describe phenomena in such diverse fields as electronics, aviation, biology, and railway engineering.
