Transcribed Image Text:**Instructional Text for Educational Website**
**Section: Beam Cross-Sectional Analysis**
**Problem Description:**
Consider the beam's cross-sectional area as shown in the accompanying figure (Figure 1). The given dimensions are:
- \( a = 4 \) inches
- \( b = 5 \) inches
- \( c = 1 \) inch
**Objective:**
Part A: Determine the moment of inertia for the beam's cross-sectional area about the \( y \)-axis. Make sure to express your answer to three significant figures and include the appropriate units.
**Diagram Explanation:**
- The diagram displays a U-shaped cross-section of a beam.
- The cross-section includes:
- Two vertical sections (flanges) each with a width of \( c = 1 \) inch and a height of \( b = 5 \) inches.
- A horizontal section (web) connecting the flanges, with a width of \( a = 4 \) inches and a thickness of \( c = 1 \) inch.
- The \( x'x \) and \( y'y \) axes are marked on the diagram, where the \( y \)-axis is the axis about which the moment of inertia is to be calculated. The \( y \)-axis passes symmetrically through the midpoint of the web.
**Instructions for Submission:**
- Input the calculated moment of inertia \( I_y \) in the provided field, ensuring accuracy to three significant figures.
- Include appropriate units in your response (for example, in\(^4\)).
To complete this part of the assignment, click "Submit" once you have entered your calculated value and units. You have the option to request an answer if needed.
