A wonderful explanation 🎉

Thank you very much , you made it very simple finding deflection by this method, I was trying to find deflection between A and D but not able to solve by integration method in finding moment area between point say A and E , as limits are not known of unknown points. Kindly look into this problem if possible.

Well done man... You describe all the thing 😊😊👍👍

such a good video. thanks!

Wonderful sir you made the concept so easy

Thanks for clarification

Nice video sir..

Sir, In the BMD for portion B to C, shouldn't the point go upto -120 not -90 at B from point C ,considering the moment of the UDL is 120kN.m? Can you describe please?

Bro you are too good ❤💕

But when i took the t(c/a) the thita a is coming out as (52.5)/EI anticlock wise is it correct plz...clarify

lovely video

where can i learn more on the table you used for this method. youre the first video ive come across using that

What is difference between slope ab and slope ba

Finding area of cubic curve isn't difficult. You can finding area of any degree curve using the genral formula... Area of nth curve: An= b*h/(n+1) So cubic means n=3 so....A= bh/4...where b would be the base(x) and h be the height(y). The CG in x direction in figure....from B X'=b (n+1)/(n+2) In y direction from the base... Y'= h (n+1)/(2n + 1) So for cubic...X= 4/5 b Y=4/7 h Also for parabola n=2 obviously Also if it's outward parabola or any curve...just minus the area from bh So outward cubic is bh-(bh/4) is 3bh/4... i mean the outward and inward together makes a rectangle anyway.

😊

sir i have solved it myself. but not getting your answer. i have checked my paper again and again.

Bro point B bm is wrong on left

The region between A and B is hogging as per the moment which means the slope you are calculating for B is opposite in direction. I think your elastic curve is wrong

Isnt that the hogging elastic curve at 24:41 ? what is wrong in that ?

The 30kN force is attempting to make the beam “hog”, however the UDL of 20kN/m * 3m overpowers that load and creates the deflected shape as shown. He is right. :)
