Sir ,the elasticity of a steel object is greater than the vulcanized rubber because by the youngs modulli,elasticity=f×l/a×del l and for steel f to cause a specific change is very large - hence its elasticity is also high.

No, diamond is hard but not elastic. It does not have tendency to regain shape after deformation. Also, it is hard not because of attraction but because of tetrahedral structure.
Please koi help karo meri me physics saleem sir se padhta hu aur me abhi kinematics par hu aur sir rotation par to me live konse chapter se padhu please help me
you must study in study in sequence -NLM,friction,circular motion, work power and energy,center of mass then rotational motion.saleem sie ne khud 8-10 baar kaha hai"nlm,friction .. ye chapeters hi poori mechanics mein aate hain aur agar aapne inhe sequence mein nhi padha to aapko kuch smjh nhi aayega" aur wasie bhi agar abhi kinematics ke baad sir ki rotational ke live lectures attend kroge bhi to kuch smjh hi nhi aayega fir kya hi mtlb reh jayega liv lecture dekhne ka,to better hai sequence mein padho . aap live lectures properties of solids se dekh skte hain 'shayad'. because as such use hi hai wahan mechanics ki boht hi basic hi cheeze lagti hain.
Sir steel hoga because koi bhi Chiz ki elasticity jo hai depend karti hai ki koi bhi chiz stretched hone par apne normal state par kitne jaldi aati hai wahi uski elasticity kahlaati hai.

hooke's law: stress directly prop. to strain. k = modulus of elasticity.. jitna jayda k , utna jyda elastic. and utna kam deformation and utna jyda stress[ mtlb jyda restoring force/area] k is property of material & temp.

K jitna Jayda hoga wo utna elastic hoga right? So elasticity jitni hogi deform hona utna ezy hoga na

Humara school mai bhi first class mai mam ne yahi same question pucha tha 😂😂
aur tujhe aaj tak uska ans dena nhi aya😂😂😂🤣🤣
@@MUIKakarot-fx5xk steel hai be, jyada Gyan le liya kya school se school boy.

Please koi help karo meri me physics saleem sir se padhta hu aur me abhi kinematics par hu aur sir rotation par to me live konse chapter se padhu please help me
Wave theory, jab Saleem sir karwayenge tab waha se live class saath me suru kar skte ho ,, baaki abhi maja karo
you must study in study in sequence -NLM,friction,circular motion, work power and energy,center of mass then rotational motion.saleem sie ne khud 8-10 baar kaha hai"nlm,friction .. ye chapeters hi poori mechanics mein aate hain aur agar aapne inhe sequence mein nhi padha to aapko kuch smjh nhi aayega" aur wasie bhi agar abhi kinematics ke baad sir ki rotational ke live lectures attend kroge bhi to kuch smjh hi nhi aayega fir kya hi mtlb reh jayega liv lecture dekhne ka,to better hai sequence mein padho . aap live lectures properties of solids se dekh skte hain 'shayad'. because as such use hi hai wahan mechanics ki boht hi basic hi cheeze lagti hain.
@@palaksagar33 Thanks sister☺️
Follow shobit nirwan advice. Unki ek video hai 11th wasted wali, vo dekho. Sare doubts clear ho jayenge
sir shear stress and strain me koi mota book leke dikha skte h kya aise confusion ho rha ha aurlanguagebhi dhang se nhi samjh aya
Sir steel hoga because koi bhi
Chiz ki elasticity jo hai depend karti hai ki koi bhi chiz stretched hone par apne normal state par kitne jaldi aati hai wahi uski elasticity kahlaati hai.
Sorry meri English jyada achhi nahi hai 😂.
But sir bata dena Mera ans sahi hai ya galat.
Muzhe pehle se hi pta tha😢
Right hai answer
Agar rotation nahi padha toh kya yeh padh sakte jai kya??
Yes

1:01 , sir hamne dm mass kyu ni liya us chhote se lenghth dx ka
Le skta hai, x•dm = x•(dx•m/l)
