**Cross-Section Calculation** For the cross section shown in the figure, calculate the following: ### Diagram Explanation: The diagram shows an L-shaped cross section composed of two rectangles, labeled 1 and 2. It includes the following components: - **Rectangle 1:** - Oriented vertically - Height (\( h'' \)) - Thickness (\( t'' \)) - **Rectangle 2:** - Oriented horizontally - Width (\( b'' \)) - Thickness (\( t'' \)) - **Reference Point (O):** - Located at the intersection of the x and y axes. - **Coordinates of Center of Mass (C):** - Represented as \( ( \bar{x}, \bar{y} ) \). ### Axes: - **y-axis:** Vertical direction from point O. - **x-axis:** Horizontal direction from point O. - \( x_c \) and \( y_c \) indicate distances from O to the center of mass (C) along the x and y axes, respectively. ### Dimensions: - Base width (\( b \)) = 8 inches - Height (\( h \)) = 7.6 inches - Thickness (\( t \)) = 2.6 inches To solve the given problem, utilize these dimensions and calculate based on the properties of the L-shaped section using geometric and centroid formulas.
