Introduction to internal forces

This engineering statics tutorial introduces internal forces in members. The internal forces that we look at here are axial force, shear force, and internal bending moment. If you “virtually cut” a member and remove one side, the part that remains must still be in static equilibrium. It’s the internal forces that are transferred across the virtual cut that keep each side in static equilibrium.

Looking for practice problems with solutions? I also created a whole set of fully solved statics problems with step-by-step hand calculations:

Looking for software? I highly recommend checking out SkyCiv. They make a full suite of online structural analysis software and tools that are useful for both students and professionals, including calculators for beams, trusses, frames, moment of inertia and more. It’s great for checking your work:

As a mostly uninterested Mechanical Engineering student I was failing my classes and did not have the motivation to study. Your videos are a life saver and the clarity and simplicity of them gives me more reason to study than the classes I have failed ever could. Thank you.

tysm for this playlist. It's 3am and I've been watching these as a refresher for tomorrow's final.

Thank you for making this video. It really helped me understand everything I needed to know.

Can you explain how you got 6m for By and 4m for 15kN?

Thanks for the video. When question asks shear force at point C, should we say +5 or -5 ?

Thank you for the interesting video. Could you be so nice and tell me what software did you use to make the video? Is it some kind of whiteboard soft? Tnx in advance.

@Engineer4Free Could you explain why the the moment at left in anti-clockwise at 6:24

[coltonmcdorman]

why didn't you include the 15 kn in the EFy on the right side

I think this is a faulty setup. A won't resist any moment and B won't resist lateral movement. There is no additional support in between A and B. There is a hinge and we are loading this span.
The span will just fold at the hinge.

Mechanical lesson should be easy not complicated for that reason iam out 😂

huh.... he posted this on may 4th and he's talking about forces....
