That's quite understandable, thank you sir.

Hi thank you for the amazing videos! What do you mean by smiley face when you talk about the direction of the moment?

Sir, if forces are passing through longitudinal axis of bar, it will not cause torsion, like in the example above if Fx and Fz are passing through centroid of the cross sectional area, then these forces will not cause any torsion. is that correct observation ? thank you
