AI Thread Summary
When a rope is cut, there is a delay before a person becomes unbalanced and starts to fall, due to the speed of sound in the rope affecting how quickly the change in tension propagates. This delay is similar to the behavior observed in a slinky, where the bottom end remains stationary until the disturbance travels through the entire length. The phenomenon highlights the importance of tension dynamics in understanding balance and falling. Overall, the timing of the fall is influenced by the physical properties of the rope. Understanding these principles can clarify the mechanics of falling after a rope is cut.

... and then someone cuts it, at which point will I become unbalanced i.e. start to fall?

is there a delay from when the rope is cut to when I start to fall?

Hello ayzd, :welcome:

Good question.
The speed with which a change in tension propagates through the rope is the speed of sound in the rope, so: yes, there is a delay.

For comparison:
There are some nice videos where someone let's go of a slinky and you see the bottom end of the slinky stays in the same position in the air until the 'disturbance' has traveled from the top end to the bottom end.

I think it's easist first to watch a short vidio clip I find these videos very relaxing to watch .. I got to thinking is this being done in the most efficient way? The sand has to be suspended in the water to move it to the outlet ... The faster the water , the more turbulance and the sand stays suspended, so it seems to me the rule of thumb is the hose be aimed towards the outlet at all times .. Many times the workers hit the sand directly which will greatly reduce the water...
