For shear stresses (VQ/It) the neutral axis is perpendicular to the shear force V that caused the stress. For bending moments (My/I) the neutral axis is the axis that that moment is bending about.
What about the stress components at point C? I tried them on my own and I think I found the bending stress to be 106.95 MPa in compression and the shear stress to be 15.34 MPa in tension at point C. Not sure if these are correct.
you are a saint for making these videos, man. It's very hard to find thorough explanations such as yours.
Your videos are so helpful!
this is awesome! defiantly helped on my final exam in mechanics!
Your work is nicely laid out and it helped a lot don't listen to these bots. 👍 cheers
thanks for this excellent lecture
10 :46 sir please tell about how we select neutral axis
you had chosed NA on y axis
can we choose NA on x axis?
PLEASE REPLY?

Wouldn’t the weight of the sign affect the sum of forces in the Z direction?
no information about weight. so you ought to accept it as a weightless objevt.
missed Mz on point C, which gives the same value of MzD, but pointing to y+ axis?
amazing thank yoz
why -Mz and not My? im still 😕 😕 confused, because it's -(3000)(3,5)
ohh i see now...
your work is not NEAT
Ouch!! Will try to do better next time, Dineth!
make a better video then
Works all over the place… if more nicely presented it would be great
Ooof… thanks for the feedback! Maybe some of my other videos are better!
Everyone else understood it fine. Maybe it's just you.
