To calculate the location of the centroid for a composite area. The beam section shown in figure (Figure 1) has dimensions H₁ = 20 mm, H₂ = 8 mm, W₁ = 11 mm, W₂ = 23 mm, and R = 6 mm. Determine the location of the centroid. Use the table below to organize your calculations. For regions that are holes, the area is negative.
