really help in understanding the concept. I always think about why i chose engineering and that'd absolutely the worst choice i've ever made in my life until watch your videos
Could you give me an explanation to how this internal moment appears? Does it mean that you bend it from top and bottom or from the sides, I can't really see it. Like where is this stress located? I love the videos man!
Hey thanks Philip. Yeah in this video, we're looking at the cross section aka "front" or "down the barrel" of a beam. From your perspective, the beam is going into/out of the screen. If you looked at your screen from the side, the beam thats passing through would be bent concave up, or appear like a bit of a smile - if it was deformed enough to see, the ends would be up a bit and the middle would be down a bit. It's a classic case of pure bending, I recommend going through videos 22 - 28 here: engineer4free.com/mechanics-of-materials some of the videos present the cross sectional view like this and others show the side view. It's good to get practice recognizing what you're looking at!
These are worth watching: ua-cam.com/video/8wgwSZNxNUo/v-deo.html and ua-cam.com/video/G7pDrGU0Q_Q/v-deo.html and also exploring engineer4free.com/mechanics-of-materials in general 🙂
Understandable! On an exam you will be given a pretty hefty formula sheet, but it's good to do a lot of repetition, so that when you see the formulas, you know immediately what they are for, or if it is missing one, you know what to do. If you have the time, I recommend going through all my mechanics of materials videos here: engineer4free.com/mechanics-of-materials It will expose you to more explanations and examples than just your course material, and the extra time spent with all the formulas will help

Great explanation. Good videos! Please keep them coming.
Thanks for the encouragement!! I plan on making many more :D
Cranking out content man! Nice!!

@@Engineer4Free Now I can see it, knowing its the cross section! Thanks alot :)
Do you have a modulus of elasticity video? Where MoE = Stress/Strain

Appreciate the explanation, but i'm overwhelmed by the amount of Formulas, do they have to be memorized or are they just their for proofing?
