Learning Goal: To calculate the location of the centroid for a composite area. The beam section shown in figure (Figure 1) has dimensions H = 28 mm, H = 11 mm, W = 10 mm, W 21 mm, and R = 4 mm. Determine the location of the centroid. Use the table below to organize your calculations. For regions that are holes, the area is negative. Calculate the product of the area and z for region 1. Express your answer in mm to three significant figures.
