(11-2) SFD & BMD with Graphical Method #1

This video recaps how to construct a shear force diagram (SFD) and bending moment diagram (BMD) using the graphical method. This is done for a shaft which is loaded with point forces only.

Hi there, I understand SFD and BMD fully from your video. You're really a very good explicator - easy way you can explain a difficult thing. What an excellent lecturer you are ! - Engr. M. G. Mustafa

[@fahadjaved904]

the way you explain things is WOW Also your voice is so sweet ♥♥ in love with your voice ♥♥♥♥ keep saving our semesters

breh

[@ikramullahkhan9532]

Really u explained in very well mannered I understood everything ❤️

[@jossy2714]

U r my hero. God bless you.

[@anasahmed585]

Explained very well. Thanks alot.

[@moazbilal3051]

good video in good time tanks a lot

[@CivilThinking]

Good teaching

[@NexusNomad00]

well explained.

[@nutsuloid1887]

great videos!

[@thelecturetheatre]

Do you use scale when drawing the shear force diagram? eg. how to draw 371N up?

[@bikebuilder17]

explained very well! Do you happen to have examples of horizontal AND vertical forces? Thanks!

[@theryderproject5053]

I don't think so. But for horizontal forces it would be axial loads so you should search for axial load diagrams. It's pretty much the same thing. :)

[@fauzydanny360]

Where is the maximum bending moment point will be based on the bending moment diagram?

[@fionawyer5610]

I believe in the BMD the solution to (129.85+11)*0.5 should equal 70.425 Nm instead. The error then carries to the last solution not ending back at 0.

[@fionawyer5610]

I now realise it's calculated 129.85+(11*0.5), so please forget my above comment.

[@theryderproject5053]

I think my solution is good - it's just that you have got the brackets incorrect in yours. Should be 129.85+(11*0.5) rather than (129.85+11)*0.5).

[@xrhst0s2114]

what if the force goes up but it negative sign? From where do we start left or right?

[@mustafaelnagar8618]

Thanks

[@hosamalhunaity7362]

what is the name of the app. you writing on?

[@cablestick]

Hi Sarah, in your previous video you mentioned that moments need to be considered differently i.e. clockwise = positive moment, anti-clockwise = negative moment. How come the moments for the fixed joints on A and D have not been considered?

[@theryderproject5053]

It's because they aren't fixed joints - they're treated as roller joints. The question also states that A and D only exert vertical forces.

[@maxvicky4308]

I need help regarding a question. I want design shaft for shredding / metal crushing machine. can you tell me how to make free body diagram for that. because you know the shaft is hexagon shape and loaded with many cutting blades in shaft.

[@theryderproject5053]

You'd need to quantify the forces acting on the shaft...

[@bowodesign9389]

i have a question

[@yogesh1760]

Can you solve me a problem regarding sfd and bmd of gears and bearings

[@theryderproject5053]

The principles are exactly the same - it doesn't matter whether it is gears and bearings or anything else. You just need to quantify the forces and moments, then follow the process in the videos.

[@z.r1999]

it ends up with -0.03

[@medimpleboi]

Very irritating voice affectation, felt like mucus is stuck in your throat. Please speak in ur natural voice which was so sweet. 🙂
