Mechanical Engineering: Ch 12: Moment of Inertia (5 of 97) What is 'First Moment of Area'?

In this video I will explain what is the “first moment of area”?

Next video in this series can be seen at:

Best educational youtube channel! you are literally saving my life <3

Finally...Non of the videos described the definition of the 1st moment of area. But this one does, Thanks

Confused as to why there isn't a diagonal line on his graph with a slope of 1? For example if you were to take the integral of the function y = x with respect to x, the graph would show a diagonal line increasing at a slope of 1/1 from the origin of the graph, and the integral would give you the area under that diagnoal line. Why isn't that the case here except along the Y axis?

What's the yellow toy on the corner of the board? :D

dude, you are awesome. congratulations from brazil

thank you for the explanation, really helpful and understandable!

A man of enormous erudition. I love watching his programmes

For the two diagrams of the triangles. Is should be with respect to Y-axis shouldn't it? because the larger the moment as we increase the distance from the x-axis with respect to y-axis

Hello, I hope someone can answer my question. How about for the first moment area of a triangle, what would we the equation? What would be the value of a? Would the height considered be still 1/2 or 1/3? The triangle is not inverted.

Sir thank u so much for this😇 I really appreciate it👌
