- Hey everyone, welcome to my 6th video on GATE ARCHITECTURE.
This video is the 2nd part of the 4 part video series on SECTION 3 - Building and Structures.
In the video, we talk about - Shear Force and Bending Moment.
We look into a few formulas and solve some problems.
Please watch the whole video so you can get a grasp of the whole concept which will then allow you to solve any problem related to it very easily.
Hope you like the video and please do share it with your friends and colleagues and subscribe to the channel.
Thank you :)

Never in my life i would have understood SFD BMD only this video has taught me how to do it.
🔥
Thank you so much Sir..very nicely explained 💯
Amazing..I never was able to understood BMD and SFD in college properly.
hello....this year I'll appear for GATE...I've watched some of ur videos and are very helpful...can you please upload more videos so that it can also cover the other parts of the syllabus...
Thank your sir..😀
You have made it so simple 👍
Thank you .. its very very helpful
Welcome Disha ☺️
at 1:01:54 the force which we get is 2 KN, but shouldn't it be the reaction force at either side? Since the moment of 10KN is acting at the middle point so how come the force of 2KN acting at the same point generates the moment of 10 KN at that very point? I = FxD, D=5, the force (2KN) should also be at 5m dist.
Hi Gaurav...I didn't get your question, nevertheless, I'd like to clarify.
This question involves a two-step process.
You first have to figure out the moment, then from the moment, you calculate the force acting downward.
Thus we convert the FORCE = 100KN acting SIDEWAYS to a MOMENT = 10KNm ( Kilo Newton Meter, be aware of the units ).
Then using the MOMENT = 10KNm we calculate the FORCE = 2KN by the formula MOMENT (M) = FORCE (F) X DISTANCE (d).
We apply the values and get the FORCE = 2KN AT THE SAME POINT.
Remember we cannot divide the MOMENT =10KNm into REACTION FORCES, for that we need to find the FORCE at that point which comes out to be 2KN.
I suggest you rewatch that portion carefully and pay attention to the UNITS of FORCE and MOMENTS.
I hope this helps :)
@@StoriesofArchitecture the moment is 10KN, and hence we get 2KN force by the formula force x distance. Now, my query is, if the force of 2KN is acting on the same point as of Moment, distance will be zero.
If we are taking distance as 5m, therefore, the force is acting at 5m distance not at the same point?
@@GauravKumar-md4se I am also confusing in this step , please clarify
Very well explained sir...thanku
hello.. why B.M at end points of a simply supported beam is 0. when it is an internal resistance(a resistance by the rigid material of the structure) to the moment caused by load applied. can you explain it?
huge …. respect for u sir
Thank you
Good to know you found it useful. :)
Can you please solve gate 2017 question no 37
38:06 why (5*2) on RHS not taken? Doubt...
cause the BM is being calculated along point C. M(c)
hey hi...
just a query...will the f1 at LHS be positive...as anticlockwise and in LHS
Similarly f4 at RHS be negative...?@16:10
Hey Priyanka... Look again at 12:00 How I explain sign conventions... LHS = Clockwise is +ve and RHS = Anticlockwise is +ve.... Similarly LHS = Anticlockwise is -ve and RHS = Clockwise is -ve...
@@StoriesofArchitecture yaa.. got u.. thank you...
@@thetrip_withn_architect Good...Always make that small sign convention diagram when in doubt... Also new video is up...Do watch..Like and share :) All the best for your preparations... :)
@@StoriesofArchitecture Thank you.... will surely watch...
Hi sir...how is Ht of BMD equals area under shear force???
(As SF area is 36 and ht of BMD should be 36 at 26 min !!!)
Hi Shivani... at 26:00 Shear force = 6KN x 3m = 18KNm ...
Hence the height of the Bending Moment diagram is 18KNm...
Should we consider only positive area??
@@shivanikomati3648 No... The Positive area increases the HEIGHT of Bending Moment diagram and thus it goes from 0KNm to +18KNm height...
The Negative area decreases the HEIGHT of Bending Moment diagram and thus makes it go to back to 0KNm from +18KNm as 18-18 = 0...
So it will be 36KN ??
Okk..I got it now thanks!!!!! :)
