Question
The cross-sectional area of a wide-flange I-beam has the dimensions shown. Obtain a close approximation to the handbook value of \( \bar{I}_{x} = 654 \, \text{in.}^4 \) by treating the section as being composed of three rectangles. ### Image Explanation: The diagram displays a wide-flange I-beam with dimensions labeled. The beam is oriented vertically with its flanges (horizontal parts) on top and bottom, and the web (vertical part) connecting them. - **Flange Width**: 7.073 inches - **Flange Thickness**: 0.628 inches - **Web Height**: 16.25 inches - **Web Thickness**: 0.380 inches The coordinate axes \( x \) and \( y \) are indicated, with the \( x \)-axis along the length of the flanges. Below the diagram, there’s a prompt for the user to input the calculated value of \( \bar{I}_{x} \), the moment of inertia around the x-axis, in square inches. **Answer: \( \bar{I}_{x} = \) _______ in.\(^4\)**
