Analysis of Strain IV

[@pranav9339]

28:13 why does steel rod deform more than aluminium rod? I know it's a practical observation, but is there any theoretical reason behind it? Can anyone address my doubt? Thanks.

[@asgeirnilsen6752]

example 3. epsilon_s not equal to epsilon_c. del_s equal to del_c. The steel and the cobber rods have different length. Thanks.

thank you prof. i wish for you, long life and prosperity

[@germanosorio9979]

Prof. Please could you explain in the lecture 10 Analysis of Strain IV about the problem 3 how do you obtain W = 789.6 KN Thank you very much for your support.

thanks prof. uv made it easy 2 understand now.

If a bar is placed on frictional surface then what would be the stress shear? developed ??

Sir Ex pm-3 'pc=27/40ps' from where did we u get 27/40 sir if we know, Then only we can get 'w' value I think not only me everyone has same dout

Professor , u are best .

@nptelhrd @iit_kharagpur voice is not audible. Plz Look in the matter.

Profesor, please, could you explain how do you obtain w = 789.6 kn. Thanks in advance

Problem 2 should we take 35MPa as negative?

[@MsRoughman]

Nice Lecture sir. I've a doubt. In the above example problem 3 u have written the first equilibrium equation considering the forces in both the copper rods as 2P Cu, but in the last lecture u had considered the equilibrium equation with just one single force combinedly for two copper rods as P Cu. This is a bit confusing. Can u help me out with this?

[@adityamehra7238]

that is because there are rods here, 2 of them and in the last lecture it was a sleeve, i guess.. which was 1 single offering the strength

[@meetpatel-lf8dh]

@@adityamehra7238 exactly !

[@puspenduroychowdhury4534]

example problem-3 Ec=120Gpa.Not 120Mpa

[@santhanakumar.a5586]

Thank bro ...for a while I got confused

[@saicharangarrepalli9590]

In example number 3, if the strains are equal, the deformations are not, as the bars are of unequal lengths. I think you need to equate the deformations instead of the strains.

[@jshkumar2]

YES , YOU ARE CORRECT
