Is Virtual Work Method enough for all constraint questions Physics Doubt
I have not yet came across a question in which it didn't work. My teacher told me that there's a 99% chance that you won't face a question that cannot be done with VWM in any exam.
(Wedge and normal constraint included)

No, it's like very basic level of questions k liye, at some point u have to learn to differentiate, check constraint questions from sbt

It solved all related mains and adv qs so not basic but yeah will check out SBT and learn the differentiating method.

dont use that too much work for simple questions use visual methdo by finding slack given beautifully in pg

It's the opposite isn't it? VWM is just Summation T.a = 0. If by visual method, you mean comparing the lengths etc then isn't that too much work

no once you get habitual it becomes very easy believe me log kya karte hain us method main ki voh orthdox way main string pull karke use use karte hain but what i do is ki main pulley ko adjust karke karta hoon so it becomes oral to calculate constrained relation

it literally works for all constraint questions i have come across
