S2 RARE: Episode 3: Amazing Short Trick. Simple Harmonic Motion. Jee Advanced.

In this episode, I show you a mind-blowing trick to solve complex pulley problems in Simple Harmonic Motion.

[attharvagupta]

sir this is some god level trick
thank you very much for this trick.

[dhruvchaudhary]

I derived this from constraint equation

[rajx____]

My teacher taught this and this really makes the Q so much easier !!

[shivanshmehra]

Thank you very much sir
Can you tell me what to do in these type of questions if pulleys have mass as well? Thanks!

[bhaswatisur]

Sir, thank you very much. This formula is really very helpful.

[terabaap]

Please start a sure short series for jee 2022

[victori]

Thank you for the formula, it really made my day!! :)

[anshumansingh]

Thank you sir
Now these questions are cake walk for me.

[rajankit]

I know this, it is called energy method. Energy of the spring can be written as T^2/2K where T is the tension in the spring. Plz correct me if I'm wrong...

[sakethkashyapnagendra]

4k/21 ! Made a calculation mistake the first time, will be more careful from next time onwards !

[arkraj]

My name ain’t Aproov it’s Apoorv. 😂😂 Great seeing you (at least hearing you) again sir!

[dreamyadav]

Sir i knew it before. But not familier much with questions. Sir u ❤ explained it in op way.
Thank u sir.
My answer coming is 4k/21 . Is it right sir?

[thedumbospiitropar_]

Sir please do mention the conditions appiled to this trick else it may be fatal. But nice one though. How di we apply it to a system having multiple masses at multiple ends?

[VIBERSTAR-.]

Thank you sir for shortcut and upload more videos sir ❤️💕

[Shikhar]

Seriously Sir ? This was the only question I couldn't understand when my teacher Solved it ! Thanks a tonn 🌈

[Nishant-usil]

SIRR I DIDNT GET DERIVATION PLSSS GET ONE VID OF THAT

[anubhabgoswami]

Does it work if the pulleys are not massless, i.e. when the pulley rotates too?

[mrunmayikulkarni]

Sir is formula common for both series and parallel arrangement of springs?

[K_PRIYAM]

Sir what if two pulley is directly attached to the block via spring of (different k), which one we will assign the tension first.

[PK-ebgs]

Keq = 4K/21, This is my answer for the last question
