I mean, if it went down, would you be asking this question?

For the sake of this experiment, it probably goes up. However, most comments forget that whether it goes up or not, depends on the elastic band extension compared to the additional length on the red/blue threads. Since spring extension is linear with force, the extension would be halved when the system turns parallel. This half distance may or may not dominate the excess string length here. The information from the video is insufficient to determine whether the new equilibriun is higher or lower uneless you manage to extrapolate spring stiffness from it.

I love that Steve Mould did this so long ago. I keep thinking he reposted

Well the spring are in series right now so spring constant is k1k2/k1+k2 <k1,k2. When the string will be cut the springs will be in parallel which means spring constant is k1+ k2. Since the value of spring constant has increased but the force(mg) has remained the same by using kx=mg we can deduce that the elongation will decrease i.e. weight moves up. P.S. I think I am right but I could be wrong.

Up. The springs will be "in parallel" after cutting the rope. Therefore distributing the force of the weight between the two, while currently they are both carrying the entire weight (like a circuit in series).

Rise up. The spring element goes from being in series to being in parallel. This effectively increases the k value and pulls the weight higher.

I honestly love these posts about old videos because I get to test if I actually learned/remember anything from a video I watched more than a year ago. I remembered this one and the 100 prisoners problem.

When the green rope is cut, the series connection of the springs would become parallel connection which would increase the net stiffness hence the deformation of the spring would be reduced. Means the weight will move up ☝🏻

In the first few milliseconds, the tension in the rope you cut will drop the weight a tiny amount. But almost immediately thereafter, the springs will contract, and the ropes not under tension will be pulled tight by the springs. Then, being lifted by the tension from both springs, the weight will rise.

1st the wt. Is distributed b/w the the 1st ring and the 2nd spring with the balck string tension so, 1st spring is free then it is distributed with red string tension with 2nd ring and the 1st spring so before the 2nd ring has to take 50% wt. But now only need to take the rest of wt. After the string tension So it has to move up

It'll stay roughly in place: the springs will shrink in time to hold the weight in the same place it was initially

Because we're going from having the springs in series, where they each carry the full weight, to parallel, where they each carry half the weight, the amount the springs are extended will halve. It could go up, depending on how much slack is in the ropes, and how long the neutral position of the spring is.

It will go down initially. The real question is, where will it settle? That depends on the weight v.s. the pulling power of the springs.

Tbh due to the distance and the lighting i saw this gif multiple times before watching the video thinking the spring was actually some ball chain so i couldn't make sense of the weight going up.

The load on each spring halves therefore the springs will retract to half of their current length raising the weight accordingly.

What will happen to this weight when the green rope is cut? - https://youtu.be/-QTkPfq7w1A
- The weight will drop
- The weight will rise
- Nothing
