Lecture 6 : Tutorial - I

[@anandh1967]

The maximum bending moment occurs at 3.5m and its value is 11.25kN-m. Thanks so much Sir.

[@cooldevil098]

While calculating Mx from 0 to 6m, why is Ma not taken in calculation? Shouldn't the equation be Ma - Mx + Ay.x - 10.x.x/2 = 0

[@RC-jx9nw]

yes I was thinking exactly the same thing

[@HarshKumar-gc4xj]

That's why he couldn't get the bmd correct from the equation. That was a calculation mistake.

[@aditikhandelwal7992]

Yaa I am also totally agree with you

[@structuralanalysis-i947]

During the discussion in the class Ma(=-50kNm) was missed somehow. But the recorded video was edited later. Please see at 21:42. The confusion created due to the unintentional mistake highly regretted. Please note that the final bending moment diagram is correct.

[@zoteasailofs1526]

same here

[@TableeghPortal]

While calculating Ma before the section x-x is taken, we can use this equation also 10x8x4 - ByX2- CyX6. But the value of Ma comes different according to this equation.

At 26:10, bending moment diagram is wrong, because when we put x=0 in BM equation that we derive, we get zero. So graph will be starting from 0 at end A and going on increasing at the point where SF is zero in diagram, and then decrease. Sir ur diagram of BM at left side( where SF is zero) is wrong.

[@amlanjyotisarmah2284]

Sir the equation of Mx should be Mx=35x - 5x^2 + 50 because Ma=-50 knm so when taken right side the sign would change to +ve

[@ScholarStream_25]

@@amlanjyotisarmah2284 it remains negative only. We got minus while calculating so it depicts that the sense was ccw . And according to sign convection ccw is negative

[@bilalpt8526]

Why you have not considered the rxn (By) of internal hinge for further calculations from 13:40 onwards, actually (By) is not equal to Zero.

[@krishnakashyap5492]

While drawing the S.F.D at 23:29, from the equation : Vx=35-10x, at x=6 it gives Vx=-25. NOT as shown i.e Vx=-15. Is it correct @Structual Analysis - I ??

[@abranbsingh1024]

same here...it should've been - 25KN

[@sanatanibairagibabadhaumi]

SIR TOTAL LOAD 80KN REACTION VERTICAL 15+45+35=95 KN

[@tarunce995]

Reactions are wrong .. indeed ..its ok to be wrong

[@muzafarnajar7373]

Sir , Why there seems no relevance between Bending moment diagram and bending moment equations shown in video no. (6) .it gets confusing . Please! help me out . Thank you

Sir shall i kmow why saggimg momemt at poimt A

[@ashutoshdohare5080]

Why does the bmd start with - 50 at A..., we get 0 by the equation!!

[@subodh_k]

Sir missed Ma in eq

@@structuralanalysis-i947 thank you

[@amlanjyotisarmah2284]

Mx =50 knm when x=0 because Ma=-50knm so sign would change when taken to opposite side of equation so the BMD should start from +50 not -50 at x=0

[@dineshsolanki-bh1kn]

from where i get the assignment .. please kindly guide me

[@structuralanalysis-i947]

First assignment is already uploaded. please go to the course web page and see the announcement.

[@padmadevan3119]

Thank you sir.

[@hardiklakhani5]

Thank you

[@cemkalkan6118]

At 7:45; there are 5 unknowns not 4. Am I wrong?

[@RC-jx9nw]

you are correct however in this case we are ignoring axial force so Bx is not taken into account

[@aerodynamico6427]

What a TERRIBLE example of IIT standard teaching! Simply HORRIBLE!!!!!!
