MOMENT AREA METHOD - NUMERICAL 1 | Moment Area Method for slope and deflection

#Moment_Area_Method #Structural_Analysis
Hello and welcome to ‪@DCBAonline‬
This video lecture is a part of series based on moment area method.
This numerical covers important concepts of moment area method.
Moment area method for slope and deflection is based on geometric methods and utilizes the M/EI diagram to calculate slope and deflection.

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.

Nice video sir..

[@DCBAonline]

Thank you 😘

[@risky_world5692]

A wonderful explanation 🎉

[@ahmedhyd867]

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.

[@consultantskel8374]

Hi ... would you be able to show how to use "Double Integral Method"?

[@c.spandana9083]

Thank you sir

[@yangouyannislauryn1328]

Thanks for clarification

[@ahmetozcan7916]

such a good video. thanks!

[@MJswag2323]

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

[@DCBAonline]

Which table? At what position in the video can you mention

[@abinashkarmakar360]

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

[@jagathspoojari5805]

Wonderful sir you made the concept so easy

[@timothy4247]

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?

[@booksourexistence2153]

Thanks

18:50 to 19:60

[@gourihareesh6419]

What is difference between slope ab and slope ba

[@binayaprasaddhakal2494]

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

[@DCBAonline]

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

[@damland1357]

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. :)

[@fyrtandayywithsNy]

@@damland1357 the 30kN force does not attempt to hog the beam but the opposite tries to sag the beam and the UDL tries to hog the beam.

Bro you are too good ❤💕

[@Tracks777]

lovely video

[@souvik.fingtore]

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

[@vedanshgarg7938]

14:44

[@subhamoysaha4524]

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

[@KajalKumari-wh4oc]

😊

[@jatindhankhar4526]

Bro point B bm is wrong on left
