Question
**Problem Statement:** Determine \( I_x \) and \( I_y \) for the cross-sections shown. **Diagram Description:** The diagram illustrates a geometric shape resembling a hollow rectangular section. The outer rectangle has a total width of \( b + 2c \) and a total height of \( d + 2c \). Inside, there is a smaller rectangle with width \( b \) and height \( d \). **Key Measurements:** - Outer rectangle: - Total width = \( b + 2c \) - Total height = \( d + 2c \) - Inner rectangle: - Width = \( b \) - Height = \( d \) - The thickness of the perimeter surrounding the inner rectangle is labeled as \( c \) on all four sides. This configuration allows calculation of moments of inertia \( I_x \) and \( I_y \) using standard formulas for composite shapes by subtracting the inertial properties of the inner rectangle from the outer one.
