[@munishkumar_]

In case of partially restricted expansion (when there is gap Y), the contraction due to reaction from wall i.e. 'del L' is taken as = P.L/A.E. In this expression, where L is the original length, should not the value be considered as 'L + del LT' as the original length because the free expansion has taken place and original length is increased? Isn't the compressive force reducing this total length after free expansion?

[@pranjalshelke588]

The original length of member is less than 'L' . After expansion it attains full Length i.e L . So the resisting will be happening over length L . I guess .

[@mohanpatil8948]

I think since 'del l' is small it is neglected

[@biswabehera5580]

So as delT also changing for delL(for thermal stresse developed)

[@sarathuddagiri9853]

It isn't free to expand so..It is trying to expand.... In the process of expanding,The wall is exerting some force therefore the original length is L only

sir, incase of wall from both the sides, you have equated change in length calculated from hookes law to that we obtain from epsilon(t) formua. But hookes law may not be applicable as temperature is changed. please explain!

Can You please give the assignment or numerical problems related to these topics????

[@mannubhai0447]

Sir yadi partially restricted ke case me ham gap create nahi kare aur nahi wall lagaye toh vaha free expansion hoga aur jab aaisa hoga to stress ka value zero ho jayega. Aapke according partially restricted ke case me stress ka value zero nahi hona chahiye lekin aaisa ho raha hai jab ham na gap rakhe aur na wall lagayen. aaisa kyo ?

[@mohammadshoebakhtar2497]

Jb gap nhi rkhenge aur nahi wall to wo free expansion ka case bn jayega na fir apka doubt kya hai isme?

when we are finding the contraction in the bar due to the force P why do we take the length of the member to be "L" , it should be "L+dL" or is it the assumption that dL

Sir thermal stress depend upon resisting force aisa kah skte h kya...?

[@pk-sb9vt]

Sir it's not necessary that for partially restricted,thermal stress is not equal to zero because if Gap is greater than thermal expansion

Plz upload column lecture

[@anilpatil5248]

Sir if bar is cooled below 0 degree then which stress is produced in bar and how?

[@sumitkumaryadav3254]

Thermal stress in composite(steel and copper) system ka video banaye sir please

[@satwatsingh2341]

Thermal stress me resisting force hoga??

[@nejamuddinali3741]

P is taken as a reaction force due to wall.But here metal is not giving any resistance to us . so interestingly there no resisting force.😋

[@deeptikumarroy8630]

So in case of free expansion, there is strain but zero stress. Hence, strain may happen without stress, right?

[@Vijaykumardas29]

Ya offcourse strain is independent but stress is dependent on strain so its not necessary if there is strain then their must be stress as it is independent but ya if there is stress then their must be strain (individual ,net can be zero)

[@kc3261]

Sir jab slender bar ko dono taraf support provide Karne k bad temperature increase Karne par lateral dimensions me strain Nahi aa Sakta Jo hamne pehle neglect Kiya tha kyunki prominent diamension length tha kyunki ki bar slender tha To ab jab length par supports aa Gaye hai to material non prominent lateral diamension SE expand hone Ka try Nahi Kar sakta
