Class 11 Physics | Elasticity | #20 Metal Wires of Rods as Equivalent Spring | For JEE & NEET

[@anmolempire1197]

Woahhh 🤯🤯 Thanks you very much for giving such insight 💎💓

[@mohammadfarazuddin1661]

Sir as due to elastic nature of the wire it behaves somewhat like a spring... so will the suspended mass perform shm.. I expect a sooner reply

[@physicsgalaxyworld]

+Mohammad Farazuddin Yes it will be but only if the amplitude of shm is less than the extension in wire due to weight...

[@sarthakchoudhury5237]

Mohammad farazuddin thanku

[@vishwajeetchoudhary8264]

​​@@physicsgalaxyworldsir you mean a weight tied to a rod will perform shm when released ? I can't think it practically, how will rod perform shm (it will not shrink back ?)

[@rennysam3746]

If rod can be treated as spring, self elongation will become MGL/AY as opposed to MGL/2AY

Sir steel has more modulus of elasticity than rubber means it is more elastic than rubber or not

[@indusaini1523]

I m very confused in this plz help me.

[@vijayaprasadvatti6726]

dont get confused it is very simple. first of all leave about the basic definition of elasticity that we use in our daily life (that elastic means more expandable) now remember that elastic means stiffness thats why steel is more elastic than rubber (elastic nature, that is stiffness increases with modulus of elasticity so Y(steel)>Y(rubber) and steel cannoat be deformed with small forces where as rubber can be

Sirrr plzzz reply do these videos cover advance content too

[@ayushsaxena1164]

Sir how did you calculate k equivalent . Pls mention the laws of motion lecture no as sir i am not able to find it in my notes from your lectures.

[@physicsgalaxyworld]

Derivation is there in the book 'Physics Galaxy' Vol.1 2e

@@physicsgalaxyworld sir so i need to buy it or is it available online. 🤔🤔

[@adarshkumar4683]

It is also discussed in the last or second last video of fundamental classes of laws of motion

[@ujjwalchitransh6411]

Sir how to solve it without this trick...i mean by complete method... Can u please give m hint how to approach

[@physicsgalaxyworld]

You can use tension same in the rods in series and use the formula for Young's modulus... final result will be same... but considering equivalent springs is easier to solve...

@@physicsgalaxyworld thanks sir

[@adityaraj8159]

Sir can we say that if a rod is elogated by x then PE stored in it is 1/2kx²

[@physicsgalaxyworld]

Yes...

[@techblogger3604]

Sir when will again u going to do booster classes?... plz reply soon!

[@physicsgalaxyworld]

Cant revert on it... it will be decided by Ashish sir and he hasn't given the final schedule for booster next session...

[@adarshchaturvedi3498]

its starting in august ?
