Mechanics of Materials - 3D Combined loading example 1

[Awakentogrowth]

Why is no one saying how awesome this video is? Literally, this video is so well explained that it's insane

[carrrlos]

OMG... Thank you!!!! I was very confused with why the transverse shearing stress could be = to 0 sometimes and I spend hours trying to understand why and thanks to you I finally understand it, x1000 thanks, pls keep making videos, they're amazing!!!!

[riditasnim]

This is the best video I’ve watched on combined loading and not to mention, I haven’t understood the right hand rule for YEARS because no one has ever explained it well to me, but this video cleared up all my confusion on everything. Everything I questioned that I didn’t even understand enough to question was explained so well! I wish I found this video sooner

[hassankhalil]

Wow i cant believe how simple you have made this for me, thank you very much really appraciate it.

[bora_yazilim]

Thank you a lot for giving such a compact video, all in one concept. Our lecturer tried to teach this topic but it took his 2 hour to finish such kind a problem.

[nachoclown]

I hope you understand you have helped me and many other students before l because of this video, and I thank you for it.

[hwasky]

this really made it so much easier to understand seriously thank you !!

[Mamdouh_]

very neat and well explained, thank you

[amitthakur]

Superb..simplified..clearing lot concepts..

[goitzsquad]

Very well done and super helpful. Thanks!

In combined loading problem, are we considering a 2D square element on the surface of the member or a 3D cube stress element? I am getting confused on what the orientation of the element chosen is and how the stresses act on that element.

[williamfuentes]

hey, what app are you using? thanks for the video btw

[dingledanglson]

Really great video. I'm doing a lab on combined loading right now and I was wondering how you would calculate strain at point A in this problem if you have the modulus of elasticity?

[samkeloinnocent]

when using cross product I am getting +200 ; +300 ; +600, which is the best way of calculating the internal moments?

[madelinemcgovern]

how do you know the force in the z direction is pointing that way?

[AM-xybg]

why isn't the Fy force direction going the opposite direction considering that you got a - Fy in your calculation

[Ijee]

So basically are you saying there’s no normal force in this problem?

Only shear forces?

[williamcase]

three forces and three moments are all you need bro

[SDCB]

Thank you! I have a quick question sir. The axial force that is perpendicular to the cut will cause a normal stress, and the other two axial forces will cause torsional and shear stresses. How do we differentiate which force will cause the torsional stress and which force will cause the shear stress?

[jasonws]

Is there no quantitative way of calculating the moments other than imagining it? i tried using cross product which is M= r xF but i always get the negative of what you get for moments.So i got and pls help
