Title1F40.10 - Rising Arc in Falling Chain

Demonstrate how the inertia can create tension in a falling chain.​

Assembly Instructions

Feed beed chain into beaker, rotate the beaker frequently for best results​.​ 

**If you just drop the whole chain into the beaker rather than feeding it into the beaker, the chain will not feed out correctly.**

Operation Instructions

Find the end of the bead chain.  Hang it outside of the beaker until the chain of beads begins to feed itself out of the beaker.​

There is a limit on this arc radius because there is a limit to the velocity which the chain can reach. This limit is from the inertia of the chain at rest in the beaker. As the speed of the chain increases the impulse required to accelerate the resting chain increases, creating a tension in the chain which is pulling the chain back into the cup, when this force is equal to gravity the chain will stop accelerating. ​
