The correction note at 6:03 is incorrect. It says "4th row 3rd column", however the note is actually referring to the 4th column 3rd row, where "-6L^2" is written: This term should not be squared. It should simply be "-6L".

[@neelivenkatesh8827]

bro.. u said F1 and M1 = 0 and there will be of bending momeent at the node 3 but while solving problem u are taking M3=0 and M2=0.. I can't understand ..

[@alokkumarnyati]

F1 and M1 will not be zero ....there is a resisting moment

[@balajisharma9980]

if anyone is wondering how to solve the equations at the end , you can use the equation mode in the scientific calculator and consider 3 unknowns . enter the corresponding values and you will get the same answer although i did observe a sign error . i checked the equation and it was perfectly right . if anyone knows pls do put it up here. thank you guyz

[@mohdnisar9740]

Sir your values are wrong sir

Very good and neat explanation with clear steps. Tq sir

shear force and bending moment need to calculate for load vector..

Thank you very much. Explicitly defined.

please explain the boundary conditions what u did in the last

[@AbhishekSingh-ei6jn]

THANKU SO MUCH SIR

[@MaheshGadwantikar]

🙏My pleasure

[@raghavendranaik_61]

since we are calculated bm2 with reference of node 1 ,so bm1=0 and m2 should not zero because v.force * distance ,how do u took it as zero, is reference is node 2 for bm2? 0 is not possible practically, beam to have bm2 at centre. am i correct !!! and finally u calculated bm1 and is it zero right, because that is reference point... ? or....?

[@alekul2020]

think the value θ2 is negative = - 0.003125 ?? i dont know why u indicated a positive value? but its a good explanation all in all

[@shivasmart967]

tq sir

[@ikik790]

BRO WE ALL HAVE DOUBT AT THE POINT WHERE YOU TOOK M2 AND M3 = 0.. CLARIFY IT AND BE CLEAR :(

[@ramakantnirmalkar6660]

Thankyou sir

[@MaheshGadwantikar]

Thanks for the comments 👍

[@darshansawant5117]

Only we have to consider minus sign for theta during calculating bending movement? For calculating shear force theta will be positive right?

[@MaheshGadwantikar]

Yes..

[@seemaghogare3388]

Hello sir can you please show how to calculate the values of V2 using the calculator

[@mamidinaveen6445]

What you are saying man ... @ once you are saying that due to load there is bending moment at node 2 .. and no bm at 1,&3 ... And in boundary conditions u substituted that ( M2 = 0) ( M3=0)

[@jonet9610]

hello! why the M2 is equal to 0 ?

[@swarajchede]

Good one

Okay

[@bhavanisankar7588]

Tell mi techique of to find V2;tita3and tita2????

[@OhNoNotAGinger]

How can I numerically find the bending moment at node 2? I'm currently building a FEA engine using python

[@MaheshGadwantikar]

Please elaborate your questions, there are different aspects to calculate the bending moment.

[@OhNoNotAGinger]

I have a 20 x 20 matrix for a beam element such as yours, I have solved the vertical and rotational displacements and now I want to find the bending moment at each node/element. Do you know how?

[@niraj6142]

And for stresses... Formula is same as bar?

[@MaheshGadwantikar]

No, There Sigma= E/L( -1 1)(u1 u2)

[@dragonhot6951]

During18:36 U told that there will be Bending moment and even told us why,but during 19:45 u wrote as M2=0 ,M3=0

[@MaheshGadwantikar]

Yes

[@901-sairam6]

@@MaheshGadwantikar u said at point load we have a bending moment. why did you take zero I mean M2 is 0 ?? Be clear sir .

[@justinejacob6137]

@@901-sairam6 because no external moment is given in question. in question there is only one external force acting on the system.. no external moments

[@LokeshGanisetty-fh4ib]

​@@justinejacob6137since there is external force at 2 it will produce bending moment...

[@erraprashanth8220]

In explanation u clearly said that at roller support bending moment is presence but while doing problem you take bending moment is zero at roller support.. Can you explain ??..at Pointload also u said that bending moment is zero..

[@MaheshGadwantikar]

Hello Prashant, The bending moment is nothing but the vertical force into the distance, if moment at the same point then the bm will be zero.

Sir why the m2 = 0 pls explain me

[@MaheshGadwantikar]

Bending moment@ node 2, because the force is acting at 0 distance in node 2

Why Bending Moment at node 2 is zero

BM= Force*distance = The distance is '0' for the applied force. For more details watch another Problem on Beam (udl acts entire the span) & Subscribe the channel.
