Great video, thank you! It would be nice if you could add an example building on this video where you see if the dam would topple when comparing moments.
The width is due to it being "per unit length", I think; I think it's a good idea to assume per unit length, 1 meter or 1 foot, if it is not specified by a problem. The width is the "z" component (axis), where the x and y components (x and y axes) are what you see on the diagram. So, the 1 meter is going into the page.
my left ear enjoyed this
I didn't understand the total force is the pressure time the perpendicular area which is 10.6*1...sin45 nahnah

Hi, Thanks for your kind comments and helpful feedback! I’ll certainly bear it in mind for a future video!
How can the width be 1m if the shape of the dam is trapezoidal?
