SA07U: Shear & Moment Equations

In addition to updated, expanded, and better organized video lectures,
the course contains quizzes and other learning content.

Invaluable contributions of Galina Jorgic in designing and creating the video lectures and related content are gratefully acknowledged.

This is the most straight forward clearest explanation I have gotten 😭❤

[issswore]

The clearest explanation I ever seen . Thank you so much !!

8:41 It should be Cy not By in second equation. And you should solve the third equation before you can solve the second

At 00:18 shouldn't the M(x) = -5000+1000x-50x^2 ? As shown, the 5000 has an x multiplying it also, making the moment M(x) = -4000x-50x^2

Sweet lecture.Makes me understand easily.

8:39 in your sum of forces, your By should be Cy but other than that, great video

I have a question. I saw other persons when they cut the beam after mid span, being given the distance from origin to mid span, they will use the distance plus x2. Example, in the second example, in segment 2 after cuttting the beam after mid span, the 375 support force distance from the cut whenndoing moments would be 5m+x. Can this be done? If you do this, you get a different equation for moments

[OmarMshi]

Can you explain how the reaction forces were obtained please? It just goes from having Ay and By to the solution for Ay, so you somehow got By but you didn’t show that

[whereitreallycounts]

at around 7:20 doesn't make sense. what happened to the 4kn force of B? why isn't it from 6 to 10kn and then from 1-kn to 4kn?

[OmarMshi]

Also do you have a separate video on calculatng reaction forces and drawing BMD?

[JesusandPals]

How can V(4) = 6 kn and -4 kn at the same time? Wouldn't V(4) -4 kn where the 10 kn is applied? I suppose in reality point loads aren't really applied at exact points but I'm interested in understanding this in a bit more depth if you wouldn't mind helping me out?

[gnidnoeled]

In real world problem, when or how do we have the concentrated moment applied at beam's midpoint?

[ahmedbenlarbi]

Please how is calculated the following maximum bending moment : (WL)^2/24 .
THANKS .
