Trusses_Method of Section_Problem 2

aapne AutoCAD pass karvaya aur aap hi mechanics pass karvaoge...🙏🙏 PURA ek semester pass karvaya hai aapne ..dhanyawadd

[@nagabhushanr5599]

What happens if we take straight line to divide section instead of curve

[@ErRrsirAllinoneclasses]

Nice, questions

[@StarrySky0_0]

Sir if we cut this figure in a section then how come we can use moment in c point which is at the higher part of the section as we were considering the lower part of the section?

[@_Mohd_Fahad_]

sir your section is passing through three forces but there should be only three. sit I'm heavily confused please clear.

[@z.r1999]

Anyone ans plz Q1) Why section not straight..? Q2) WHY Fad, Fdb not considered bcz if we considered by doing this we will have more than one unknowns(means condition not fulfilled) if we take moment at c..

[@factsworlds]

Pata chala bhai Mujhe bhi batao

[@AkashKumar-uw5me]

Nice video sir it makes me to undrserstand section method of truss very easily right now...!!!Thanku so much for ur video

[@bhaskarsoman692]

Thanks a lot sir! Your videos has shown the exit path for fear of this subject from my mind!!!😊

[@SanathanDharmaa]

really fabulous teaching sir.. can i know in which institute you teach...

[@Shivanshu217]

F eb comes out to be negative. So shouldn't the force be tensile because it is considered to be compressive

[@sumanthbayya5287]

hello sir, in this sum taking the moment of C =0 , how you taking the clockwise and anti clockwise direction in the moment... i didnt understand this can you please explain...?

[@bossramnali3785]

Can't we take section passing through AB,EB, and BD sir. In that case we can find Feb very easy na?

[@srikarchin8355]

Hi Manas, could you please tell me why Fab is not considered?

[@deepakmurmu7732]

Yess actually that's what it should be, isn't it?

[@ELBAbujarAnsari]

At 8:34 why u r nt considering the force in AD or BD section? Plz reply

[@UjjwalKumar-]

Sir I have a doubt that Force EB is a clockwise

[@8thclassmahivlog988]

Sir if we take moment about 'A' ,still "only Force in EB" is unknown but answer got -45KN . Sir why?? Plz reply or clear my doubt...🙏

[@renjithkumar2645]

i cant understand how to seperate sections sir can u explain

[@spamansh1710]

sir why you are not considering Fab force

[@047_adityasharma7]

Sir can u pls tell why we take section curved and why we not take it horizontal?????

[@z.r1999]

Can u tell now if u have found the answer now

[@nilajpaul3439]

Sir if the question is given that find the force HE and if I consider F, from where I will take moment then , will the force AC and CF be zero?

[@sushyanthsridhar4972]

You drew the section cutting CE twice. Why aren't we considering the 15kN forces at H and I in our calculations?

[@basharathali8156]

Hello sir unable to understand how to cut the section and sir you are cutting 4 members . finally sir why you are neglecting member forces of other members which are not passing through point "C".Such as Member AB , DA ,DB.

[@z.r1999]

Same Q.. If u now have found the answer then guide to it please

[@debjitghosh1710]

Sir app ke lecture bahut acha hain.sir app please civil engineering drawing ke building drawing and residential building drawing ke basic ke upar video kariye to bahut acha hoga. Thank you sir.

[@ManasPatnaikofficial]

Sure Debjit your request has been noted...

[@debjitghosh1710]

Thanks sir..😇

[@kramu803]

Very good teaching sir very thanking u sir

[@janakamohotti]

sir why have you neglected forces Fab, Fad & Fbd when taking moment about C?

[@factsworlds]

Pata chala bhai kyo neglect kiye hai Mujhe bhi bataiye

[@Isaac97.6]

Same question I wanted to ask

[@mohithguptakorangi1766]

hello sir , why didn't u consider the 15kN forces at I,H when u wrote the moment at c =0 equation??? (can't we extend their line of action of forces??)

[@ManasPatnaikofficial]

Because it is above the section curve or line. All the forces that fall below the section have been considered.

[@mohithguptakorangi1766]

@@ManasPatnaikofficial so u say that we consider the forces on only one side w.r.t the point we consider??

[@ManasPatnaikofficial]

Exactly, you only consider forces on any one side of the section.

[@mohithguptakorangi1766]

@@ManasPatnaikofficial thank you sir

[@kamleshyadav1844]

Sir pls... Improve your handwriting... But your video is very helpful...special during online exam.

[@KIndu-]

Sir will you please explain to calculate force's in every member

[@vishnuteja4611]

Sir I didn't understand how to cut EB

[@harshal104]

Sir i understand rule of making section but when we have lot of sections to select then how to select that i didn't understand means you are taking diff section but i doing solving taking diff section so how to select which is better

[@subhamoysaha4524]

Sir is there no need to make the sections as straight line??

[@ManasPatnaikofficial]

Yes....there is no need..... It's could be straight as well as curves...... Main concern is to divide the truss in 2 separate sections.

[@127_aqibnabi4]

Thank You Sir

[@vikkie001]

Good lecture sir

[@abhiramp899]

Sir the Ha is in right direction . is its moment is clockwise direction???

[@mridulsharma3713]

Sir why does the forces along c are not considered I'm not getting this?

[@rajeshbabu8765]

why should u divide the diagram like parabola....we have a chance to take a straight line from AC to BE and divide the diagram...why dont you take this sir ..is their any reason

[@syedsalmanhussain]

why Ha is -45 kn? while calculating reaction forces in X direction, if i consider Ha acting towards left as -ve and all 15 kN forces acting towards right as +ve then Ha would be +ve? -Ha+15+15+15=0 Ha=45

[@ManasPatnaikofficial]

Will get back to you in a shortwhile....

[@GavEMusic]

See the directions of all the reactions (forces) acting horizontally and reactions are 1. 15 kN at I joint 2. 15 kN at H joint and 3. 15 kN at E Joint So summation of all these forces comes out to be 45 And The reaction H(acting at A) is in the same direction as the three reactions acting at I,H & E So to balance these forces It's magnitude should be exactly opposite and equal to those three reactions (acting at I, H & E) So it should be -45 So that it Balances the whole frame

[@rakeshsv674]

Yes, you are right. As you have assumed Ha towards left and got the positive value so you have to make calulations on the basis of that only.

[@Nikhil39491]

Thanks you sir❣️

Sir why didn't u neglect the force EB as it is passing through E

[@bibeksinghthakuri8273]

thanks sir ..now I can pass

[@balasankarkalambakkam4669]

Sir, you have given it should not cut more than 3 unknown member but here section line cuts 4 unknown members...

[@ramyasatyatekumudi5658]

Balasankar Kalambakkam If you watch the video again your will doubt will definitely clarified

[@vaibhavvmishraa]

Sir why we are not taking moments of F(BD),F(AB),F(AD) about C ???

[@rakeshsv674]

Because section is not passing through that members.

[@anasyaseen142]

Y u didnt took moment from A?

Sir i can not understand why u cut the sections in such a way , if i cutting the sections by other way result is not coming

same bro he cut it i understood that part but point c is outside the section no why did he take moment abt tat ? other way if u cut it u wont get 3rd equation i tried it ..
