Sounds right in theory, but the further the moment of inertia became on the chain, you will still have weight increasing by every link because of it hanging, regardless of whether the other end is still falling.

Re: Mechanical Engineering Riddle
Tweetactually i tihnk test is right because technically you could lower it at the speed of maximum velocity in which there would be no weight on any lonk of the chain just a pleathera of chain falling endlessly

Re: Mechanical Engineering Riddle
Tweetthere would be no hanging weight if it was on a frictionless spool dumping the chain at the same speed that it was falling because there would never be any pressure put on one single link it would be likt throwing a ton of chain made from paper clips out of a plane they aren't goign to break apart even though they can support no where near a ton they would all just fall as one big clump

Re: Mechanical Engineering Riddle
TweetIf you throw the chain down the hole as a clump than yes. But holding one end while throwing the rest will eventually create tension at the starting end. What is happening is there is the force of your hand holding the chain in place which in turn creates an upward force, opposite the direction the chain is falling. Thus, there is a moment of tension.
