WebExpert Answer Transcribed image text: For the plane area shown: (a) (5 points) break up the given area into a few simple components that can be found in the provided table in the appendix (b) (5 points) determine the first moment of area with respect to the r axis Qz. WebAug 1, 2024 · Specifically, we will take the first rectangular area moment integral along the x -axis, and then divide that integral by the total area to find the average coordinate. We can do something similar along the y -axis to find our ˉy value. Writing all of this out, we have the equations below. C = (ˉx, ˉy) ˉx = ∫A(dA ∗ x) A ˉy = ∫A(dA ∗ y) A
