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
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?
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.
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.

Really u explained in very well mannered I understood everything ❤️
the way you explain things is WOW
Also your voice is so sweet ♥♥ in love with your voice ♥♥♥♥
keep saving our semesters
breh
Explained very well. Thanks alot.
U r my hero. God bless you.
Good teaching
good video in good time tanks a lot
Do you use scale when drawing the shear force diagram? eg. how to draw 371N up?
explained very well! Do you happen to have examples of horizontal AND vertical forces? Thanks!
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. :)
well explained.
Where is the maximum bending moment point will be based on the bending moment diagram?
great videos!
what if the force goes up but it negative sign?
From where do we start left or right?
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?
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.
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.
You'd need to quantify the forces acting on the shaft...
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.
I now realise it's calculated 129.85+(11*0.5), so please forget my above comment.
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).
Thanks
what is the name of the app. you writing on?
Can you solve me a problem regarding sfd and bmd of gears and bearings
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.
i have a question
it ends up with -0.03
Very irritating voice affectation, felt like mucus is stuck in your throat. Please speak in ur natural voice which was so sweet. 🙂
thanks
