Quick note! When I say the area under the shear is equal to the moment, this isn't entirely accurate. What I mean by this is the integration of the shear diagram is equal to the *change* in moment. Let us know if you used this technique on your tests and assignments! Link to our original video on the same topic: ruclips.net/video/UYkH7Fxkxmo/видео.html
@@andrewalday7834 Shear force is highest at the supports. The magnitude of the shear force is the absolute value of the shear at that point, whether it's negative or positive is simply sign convention. Thus as we approach the support the shear force is increasing.
Thank you for making this difficult concept a simple process. I have one question. Why is it that when we take the sum of moments at point C (as you suggest, during a test) the only way to get By = 130kN is to make the 200kN/m moment at A positive. However, when taking sum of moments at B, as you did, the same moment is negative? Please explain.

Can you explain why the last curve of the Shear Force Diagram is negative and increasing rather than negative and decreasing?

Thank you so much. I am studying for my FE and I forgot everything hahahaha. love to see all the process again, so satisfying.
Not enough views. Amazing video!
Excellent video, very well explained. Keep it up!
Vrutant Kanakia great, thanks!

Thank you so much!!!
How is the last part increasing moments ?
Great video! Thanks. Already subscribed to u hehe
thank you soo much
no problem, thanks for the comment! glad you enjoyed the video.
My By came 110kn and Cy 70kn. I started by finding the moment at C.
I was wondering why wouldn’t the 60kn be negative..isn’t it. Downward force.
Thank u
Thank u than u than u
No problem!
