### Asymmetric I-Beam Analysis

**Problem Statement:**
Consider the asymmetric I-Beam where:
- \( a = 0.8 \, \text{in} \)
- \( b = 8 \, \text{in} \)
- \( c = 4 \, \text{in} \)

Determine the moment of inertia of the cross-sectional area shown with respect to the \( x_o - y_o \) centroidal axes.

**Diagram Explanation:**
The diagram represents an asymmetric I-Beam with the following key dimensions:
- Flange thickness at the top and bottom denoted by \( a = 0.8 \, \text{in} \).
- Width of the bottom flange, \( b = 8 \, \text{in} \).
- Width of the top flange, \( c = 4 \, \text{in} \).
- The height of the web connecting the flanges, also \( b = 8 \, \text{in} \).

The centroidal axes \( x_o \) and \( y_o \) are marked, with the vertical distance \( y \) from the top flange to the \( x_o \) axis.

**Calculated Values:**
- Moment of inertia about the \( x_o \) axis: \( I_{x_o} = 208.11 \, \text{in}^4 \)
- Moment of inertia about the \( y_o \) axis: \( I_{y_o} = 80.31573 \, \text{in}^4 \)

These moments of inertia are essential for analyzing the beam's resistance to bending and torsional loads about its centroidal axes.
