Fantastic teacher you are... God bless you.. 😇👍
Thank You So Much 🙏
Your videos are truly excellent. Thanks for sharing!
Thank u sir! I am able to understand fem just because of you .
Thank you so much..
For a beam shown in figure, determine the displacement and slope at node 2. Also find the
reaction forces and moments at node 1 and node 3. Consider E=210GPa and I = 4x10-4m4.
Sir thank you very very much,from Algeria ,your method is so easy to understand and you just explained every step,i have tried you method on the exercises of my professors and it worked very very well,.and lastly thank you so much for putting your videos in English!,much love from Algeria
Thank You, please do support our channel
Thanks it is useful and easy to understand.
Thank You So Much for your support
Thanks Buddy....
could you please clarify, why you have taken moments in different directions for element -1, in the previous step both were in same direction
Thank you
Its very very useful to those students who not afford tuition fees now a days tuition fees are in lacs
Thanks mahesh and keep it up.
Thank you Rathod ji
can you explain clearly about the bending moment for the element-1
Thank you sir
much help!
Thank you Hadley. Thanks for your Support.
I have a doubt ,
How to define directions of nodal shear forces & behind moment(Fd....&Md)???
Thankyou very much bro very useful video
Thanks Deepika, More 30+ Lecturer on Fem in playlist. Please do Subscribe to know all the videos and share with friends.
teacher from where you get this value for equation 1
Hi sir, I have a doubt instead of hinged support if they give anything else what will be the moment at that support....
Dr. your teaching way in perfectly understandable thank you i always need like you fantastic teacher god help you!!!!!💝💖💝💝💯
Thank you 🙏
🙏💞@@MaheshGadwantikar
Spr bro , its very helpfull
Thanks 😊 if you think it would be helpful for your classmates, do share..
Sir, is it using the same steps for question with fixed end at left end and vertical roller at right end?
thats usefull thanks
Thank you..
Could u do FEM for solving differential equations like:
d2u/dx2=10 in the range 0 to 10.....using the following boundary conditions
u(0)=40
u(10)=200
Using 4 elements.
Thank you so much🇸🇩✌️
more explanation for forces and moments taken in force matrix is appreciated
Thank you 👍
Hello Sir! I thanks you for your detail explanation about this lecture,but for the way you used to stiffness matrix for UDL beam is not clear for. if possible please attach it.
Very nice video. Keep it up!
Thank you brother..
You dont know how many good wishes you are getting
Thank you 💞
Thank u sir !
Thank You
Hi sir, Can you explain the Least square method and Galerkin method?
How u get eq 1 matrix values please explain sir
You do not know sir how much you helping us,without you ,we wont able to pass our exam.i do not know how can i thank you but God will do it you for me
Thank you for your valuable words..
Sir in the problem for stiffness matrix k2 you multiplied the length length of first element k1-4 instead of l=5 why sir can kindly explain
if the load is right angle triangular with zero at fix support and maximum at point 2 what will be the shear force at node 1 and 2 at 16:18
This is a fresh reminder of my third-year theory of structures. tough days those were
Is it..
@@MaheshGadwantikar initially it all looked hard but diving in everything got so easy. If only I had this tutorial back then my life would have seamless. Good job you are doing
Thank you so much Bryan.. I'm honoured..
Hi sir in the beginning you taken rotations in anti clockwise direction after that you have taken clock wise direction and anti clockwise direction in the next step why?
Eliminate the zeros first, so you're left with a 2x2 matrix right at the start instead of working on a 6x6 matrix only to throw away most of the values.
Dear Abhijeet, Some of the Steps are reduced here because I focus on other thing in this Problem, If You want to know about elimination method, watch my another video on assembly of stiffness matrix method.
Thanks for the explanation. I have one question, at 30:00 you state 'there is no shear force' and therefore f2=f3=0. There is an internal shear force in the beam (as a result from the udl) and initially I thought f2 and f3 would represent the reactions at node 2 and three just like v2 and v3 represent the deformation. But now I wonder do f2 and f3 represent point loads at the joints? In that case the statement f2=f3 is correct. So my question is what do f2 and f3 represent?
I will explain you tomorrow
😅😅😅
@@MaheshGadwantikar3 years no explanation
tnx
Thank you so much
Why we take clockwise moment at node 1?
Deflection at loads and slopes at the ends problems on simply supported at bearings. Cpara
Tq sir help me
Sir if the beam has both udl and point load at the middle how to solve
thanks sir pls upload video on PSTP (principle of minimum potential energy) and its numericals in FEM
Ok Anil Joshi, I will upload within two days. Request you to share the link with your batch mates.
Thanks sir i will definitely share :)
Actually I have FEM exam on 5th May so pls sir upload video on *Principle of minimum potential energy with problems and finite element analysis for plane stress*
Good sir
Ok Thank you so much!
Sir but why shear forces are zero???
how to calculate answers by using casico
You shown element forces acting upward f1d and f2d and f3d in the free body diagram. and you took the values as negative,why?
I have one doubt in a element 2 the length is 5 but you can write with length 4
I love you 👍👍👍
Sir please make a video on frame problem.. today or tomorrow
Ok I'll try
You teach better than my stupid University teacher , thanks so much !
Thank You So Much Sir
@@MaheshGadwantikar if only you are my teacher and i discovery your channel earlier and not one day before my exam ....
Sir explain the reaction also plzz
Okay you can find reaction support problem in my playlist.
i use only 5x5 matrix.....
F2 and f3 are the reactions at note 2 and 3 and they are not zeros
Sir this exact sum was given 🤦🏼♂️🤦🏼♂️ but today sum not attempted
Hi,
Your work here has helped me a lot with FEM. Thank you!
However, At 30:03, you said that there'll be no bending moment at node 2. I thought continuous beams have a hugging/negative moments over the supports? There ought to be a moment there since it is not a hinged connection at node 2.
sir pleas make a video on assembling the matrix for mXn matries with formula
Already Assembly of stiffness matrix video available.
@@MaheshGadwantikar link pls......
it just help to find a solution. but, please mention where it is exactly used in real life. we can't imagine our self practically
Good question, appreciated, But in this only video explained About calculation, not theory.
How did you come up with the matrix at 5:48? I can't follow the reasoning behind those entries.
thats just formula..
Sir fem subject important question chepandi
Thank you very much for this clear explanation..but are you sure that F2=F3=0? (30:23) It seems to me that F2 and F3 should be the reaction forces at the hinges 2 and 3 respectively, so they must be different than 0 (especially that u2=u3=0). Am I wrong?...However, this has not affected the accuracy of the results and the clarity of your approach. Please accept all my deep respects from Tunisia
As you said it's true, but while calculating reaction Forces both should be unknown values.
@@MaheshGadwantikar Thanks a lot for your rapid reaction :) ... all my deep respects from Tunisia
M2, M3 should be zero or M2d(1)+M2d(2)+M2 and M3d+M3d should be zero resp? As total moment at roller should be zero
This is direct stiffness method.
Could you help me out to solve beam problem of finding more variable deflection i have some solved sums but isn't clear can i send pic of that ?
Yes . You can send me
SIR WHY DID WE TAKE F2=F3=0 AND M2=M3=0
Sir YOU TOLD US WHAT TO WRITE & WHAT IS THERE BUT U DIDN'T TOLD US WHY IT IS ? LIKE WHY & WHEN V,θ,M,F ARE 0& WHEN NOT ,IF U HAVE BEEN THEN IT WOULD HAVE HELPED A LOT TO SOLVE OTHER PROBLEM ALSO
It Consume lot of time, instead I focus on problems only
can you do 1 for frame structure
Ita available
sir pls tell me how to find displacement at each node?
At each there will be 2 dof for beam element. V and tita.
@@MaheshGadwantikar whose value be zero expect tita 2 and tita 3?
The value will be zero if ends are fixed
why F2 F3 are zero, how can I achieve the node2 and node3 supporting force? thank u for answer
No vertical force available at node 2 & 3
@MaheshGadwantikar
Dear sir, f1 and f2 are the reactions at nodes 2 and 3 and they are not zeros
I am not understand to the k1,eq1
i thin this will help me more,but how can caliculate the radian value
It's not radian Val, Its just a deformation in a angular
@@MaheshGadwantikar please suggest me I want know that
Hope I explained in the video.
@@MaheshGadwantikar no, you directly added the value
OK. Please Watch another video on beam, may be I cleared in it. Else go to the description to contact me. I will send you the explanation
Thanks for sharing
This great knowledge
Would you please write the channel email so we can ask some questions with drafts
Thank you so much dear.. I will provide it in the description
@@MaheshGadwantikar Thanks alot for instant response
In bending moment at node how u got wl2/12.. please explain
For simple support beam with udl is wl2/12
@@MaheshGadwantikar maximum bending moment is wl2/8 sir
@@MaheshGadwantikar how wl2/12 please explain sir.
Evening I will explain you..mam,
@@MaheshGadwantikar one of them should be negative right ?
BRO I HAVE THIS QUESTION IN TODAY(04/02/2022) FEM EXAM....
Good
Why is F1 and M1 non zero ?
UNIFORM VARYING LOAD PROBLEMS, CAN YOU GIVE DEMO
Okay Sir, I will Find out such Problems. Thank u sir for your kind consideration
Hi sir
Why F1 & M1 valus are not taken as zero while we're taking F2,M2,F3,M3 as zero?
No force at node 1
Please clarify more
WHAT STANDS FOR F1d and F2d and M1d what d stands for
F1d=Vertical force at node 1, M1d= Couple moment at node 1
@@MaheshGadwantikar and what is v1 and v2 etc.. those are also vertical deformations right
Yes, your right..
Moment of inertia I is given for entire beam but why are u using that value of I for element 1? Because inertia for element 1 will be bd^3/12 where b is 4m for element 1
Let me explain you, the moment of inertia is given in the question that is about 4x10^-6, so you no need to calculate, any how the b and d value we don't know, and In the solution I can consider same inertia for both elements.. Please check once
And one more misunderstanding, where B is the width not the length, B is not 4m, that is the length(l) of the element 1
@@MaheshGadwantikar my B is not width. The inertia for element 1 will be 4×d^3/12 where d can be found out by equating given inertia of entire that is I= 9×d^3/12 ...from this d we can thn calculate inertia for each element because since elements are of different length we can't take inertia of entire beam equal to individual element inertia
Can you forward your questions.. Please visit my channel description, you can get my details
@@MaheshGadwantikar I have sent an email to the mail id given in description.
For me also sir unable to solve beams sums. How can I send sums sir
You mean global stiffness matrix?

F1 M1 F2 M2 F3 m3 are the reaction forces right ??
No
@@MaheshGadwantikar so which are reaction forces, f1d?
Reaction forces are R1 , R2 etc..I separately explained about reaction forces another video
@@MaheshGadwantikar what is this other video called?
what is your email?
Please check in Channel description
I don't think both conditions v2=0 and F2=0 can be met at the same time. Same remarks for v3=0 and F3=0. We overlooked this because it didn't have any incidence over the final answers as we were asked to find the rotations.
F2 and F3 is not zero, no?
Yes.
So we can calculate F1 , M1, F2 and F3?
Aap toh bhagwan ho
Thank You
i thought clockwise moment is positive
Right hand rule, counter clock wise is positive.
No not explain in proper way there is some mistakes
No proper explanation..simply waste..explain the concepts dont show your calculations
