4m (5m for UDL from the end - 1m for Rb from the end) is correct as per his explanation. Sketch a free body diagram and convert the udl into point load, you'll understand it!!

[@talibkhan1246]

Why minus 1m for Rb?

It's 7m from b to c..... So bending moment at that B will be -Rc×7 +1800×3.5 - 200 = ....... Right?

sir, please make a video on sfd and bmd for fixed beams with calculations. sir your explaination is awesome and easy to understand

[@ishank9082]

why did he took two sections for each point?

[@ankushjaswal1992]

because in udl the load is different on both side of section. e.g at point B 1st load of A = 200 n the udl load of 180*1 (1 is the distance btw a and b) and after section B we have another load of RB

On the calculation of shear force at point C when you have taken the section toward the right of C it will be +2000 in place of +1000 at the calculation time you have taken 1000 two time it should be 2000 at one place as it is the support reaction at point C you have taken it 1000 also

In Point load calculation (Previous videos) your have drawn centre line on the right side for bending moment but in this video left side for point "B" Totally confusing, To match with the answer you are switching left and right ??

[@ankushjaswal1992]

HERE IS YOUR CORRECT SOLUTION ; here is some confusion going on , the teacher just follo the book and in the book its not simplified so let me calculate for moment at B .....-RcX7 + 180X9X9/2 - 200 - 180X1x1/2 = 1000 its a very good question , the 180 udl load is ating on right and left side of the section thats why i took +180x9x9/2 on right section where as on left there is a span of 1 mtr so again - 180x1x1/2

[@niharikasharma1638]

Sir In this question, when we take moment about B, then why it is -1800×4? Why isn't it -180×5? As moment will be on the centre..

[@ankushjaswal1992]

may be = lets again draw a diagram, an u will see the total lenght is 10. now divide 10/2=5 here 5 is in ur centre but wait we have to take the centre of Rb and Rc and the distance between rb and rc is 7 so if we divide 7/2 it comes 3.5 on each side. Now the trick pART IS we have to take the centre not whole beam but between rb and rb so we know half of section = 5 and when we add 3.5 + 2 = 5.5 on RHS and 4.5 on LHS so shift .5 to LHS then it comes 1+4=5 and on RHS 3+2 = 5 it will come like this . i know u r not going to understand this but u can mail me i also made a diagraam.

[@Deadskull215]

3:34 and just ahed of ….. It’s still confusing how you can calculate distance … plz show how you calculate bcz it doesn’t seems right bcz if we take 1800 N at center at the beam which is 5mm then with respect to B Load must be at 3.5 not 4. So clarifying it properly not assume or take 4 in calculations and i am still confusing with the sign of 1800 N force in B.M calculations. 🙏🏻 anyway good effort but elaborate properly so we can easil understand.

[@fardinislam9600]

Why did we take +ve value for the 1800N force acting downwards?

[@amritanandpathak1112]

because when we sit at b, 1800N will rotate the beam in clockwise direction, clockwise is taken positive.

Shilpika Parida first take the entire udl as point load acting at the centre, then, subtract the overhanging lenght on the left of B since we are taking moment about B. That's the only possible way he could've done it,either that or he's wrong, coz udl is present over the entire lenght and hence it has to be taken as a whole.
