Series to parallel
Effective spring constant increases
@ninja_tersesatmlbb Says:
Karena tali hijau memikul berat bebannya sendiri sedangkan ketika di potong tali yang lainnya menanggung bersama beban tersebut sehingga spring bebannya berkurang.
@GabrielFederico-ct2es Says:
just cut the damn rope
@ilovesprinting2012 Says:
Honestly an unfair question because we don’t know the strength of the spring…

Somehow palpatine returned.
@hristokolev3000 Says:
The explanation i can think of is that all the weight was crried by the green rope but when they cut it the weight was held by two ropes
@Mihonisuto Says:
Do an easy force sim you will know that it will go up.
@Alidaher2468 Says:
In the initial setup:
The 2 springs where carrying the weights in series thus the equivalent stiffness is k1xk2/(k1+k2)
In the second setup:
The 2 springs are in parallel thus the equivalent stiffness is: k1+k2 which is larger than that of series case, thus same foce for both cases but in the second case higher stiffness meaning lower displacement.

parallel spring system vs linear spring system

100%=>50%
@fearsceremony Says:
This kinda seems basic. but at first glance before analyzing yeah Id say it’d drop. but once u see the springs its kinda obvious
@akshaysharits3044 Says:
Assuming the strings have 0 mass and equal length and spings have same spring constant and arr of 0 mass the system will tend to go to a low enery state so when you cut the string it tries to minimize the total energy in spring and the gravitational potential energy if you can minimize this energy you get tje solution to be spring extended by half the length they were extended in the initial state and and weitght moving up by that same amount .
@1505kartikeysingh Says:
The new equivalent spring constant would be 2K . So the elongated distance will shrink
@madisonking8057 Says:
You are switching from 2 resistors in series to 2 resistors in parallel so total reisstance will go down. The path will shorten.
@toailedanh-i9u Says:
Stupid
@Jet_fuel75 Says:
i guess that means that the green rope is really tense and is stretching the bottom spring down and the spring is simply strong enough to hold that weight up?

ilkinde tek yay kullanilmis ikinci durumda iki yay var. ilk durumda yayda gerilim fazlayken ikinci durumda yay sayisi arttigi icin gerilim azalmis
@sedik_is Says:
It seems pretty simple The reason why I would go up is because the springs were being stretched by the green line when you cut it the springs are no longer stretched which means if the top spring is tighter than the lower one it would go up when the spring tightens
@rishitiku5996 Says:
Yeah, so the tension was on the two sequential springs at the start, then when the rope was cut, it came to the two springs in parallel.
The weight remained the same, but the Tension was halved on each spring and thus they shrunk. Weight went up.
@jalalshamaa1173 Says:
It is not a fair question what if the springs can't hold the weight so we would get different results (I think)
@ZAB-ug6or Says:
I KNEW IT OMG!! For anyone who wants an explanation, it's because the thing that we cut in the end was holding the whole weight, and it was stretching the coil. When it was cut, the coil wasn't stretched by the weight anymore, and so it went up! 😊

The real gold is beside you 😅
@ABHISHEKBARALA-x2q Says:
Initially , both springs have equal tention , equals to the waight , finally waight got distributed on both springs , so tention got divided equally as half of to tal waight .
@sritharan.sri8r Says:
Little up
@UNKNOWN-MW Says:
everyone with a brain would have said up
@Tavahot Says:
It depends on the slack(surplus length) in the red and black threads.
because now the weight has two parallel springs in action, which doubles the system’s coefficient of elasticity.
Now the elongation in each spring will be half of the original. So previously if the stretch was 2y, now it will be y/2. If the loose threads are not so loose(loose less than 3y/2), weight will go up. If slack(thread surplus) is more than 3y/2 then it will go down.
@johncoptu5829 Says:
Wow, it bounces. I thought that would be obvious, but okay. 🤣
@k18-y5e Says:
Obviously duhh...
Strings are connected in parallel before cutting it and in series before cutting it
@Arvindk-gu3pk Says:
for those wondering, the springs go from being in series to in parellal.
In a spring system, the effective strength(stiffness) of a spring is far higher in parallel (Arithmetic > Harmonic)
@davidgill9509 Says:
The springs moved from series to parallel.
@baconpancakes8899 Says:
Duh?
@brenurd Says:
Skip a minute in that’s when they actually cut it
@At_Least_official Says:
After cutting the green rope it's basically two spring
@adamm5205 Says:
You dont have to carry another spring after you cut the rope.
@workhardforit Says:
It went up slightly because the weight got distributed to both springs evenly, in a parallel manner.
@gamingrevolution862 Says:
Somehow? You forgot to mention that the springs are tough
@illussionerstryder7179 Says:
The answer is initially the spring are in series and thus their spring constant is less but when we cut the string in between the spring become parallel and the spring constant increases. According to th hookes under the same force displacement in the direction of applied load is inversely proportional to spring constant. So in parallel combination that is after cutting the string as spring constant increased the displacement downside decrease and the weight goes up.
@TheMachineQuest Says:
The springs now get connected parrallel to each other, therefore the weight gets shared among bothe the springs, hence the load on each spring gets reduced by half, so they need to stretch less, therefore they go up
@GorillaGaming8 Says:
If you look closely the last once green rope is longer and another rope were already under stress.
@siamesestormtrooper Says:
For those who need it explained when both springs are tied to the mass on a single line, both springs have the full weight of the system extending them, but when he separates them into two separate lines, the weight can be distributed across both springs, reducing the length of the springs
@prasadmaddikuntla7479 Says:
Same place I guess
@calcustom5026 Says:
In the first position 100% of the weight is going through the springs as if they are one long spring. So the weight is only held up by the strength of one coil at a time regardless of how many springs are used.
When the middle connection is severed the springs stop acting like one long spring and instead act like two short springs. The weight is held up by the strength of two coils at a time. Meaning, they will have ~50% less stretch, causing the weight to not sag as low.
@AutoBodyEverything Says:
It goes from using two springs in series to using two springs in parallel. The first option lengthens the spring length but has the same strength.., second option reduces spring length but doubles the string capacity.
@mreigy Says:
2 springs has more resistance to weight than 1 spring.
@leeladhar7468 Says:
it will spontaneously combust
@filmerstudio3693 Says:
is it because the tension or mechanical force, adds energy, and energy is equal to mass, so it adds weight when subjected to direct tension. and less because the strings held it up?
@eddyjayarsinahon8433 Says:
Nobody guess it right
@samhaaf Says:
Before: the springs are in series
After: the springs are in parallel
