Question
Calculate the moment of inertia about centroidal axis.
This image appears to be a diagram of an I-beam, a structural element commonly used in construction and engineering. Below is the transcription and detailed explanation as it would appear on an educational website: --- **Understanding I-Beam Dimensions** In this diagram, we have an I-beam with the following dimensions: - **b** = 159 mm - **d** = 216 mm - **t** = 37.4 mm **Explanation of the Diagram:** 1. **I-Beam Cross-Section Layout**: - The diagram shows the cross-sectional view of an I-beam, which resembles the letter 'I'. This structure provides high load-bearing strength and efficiency. 2. **Dimensions**: - **b (Flange Width)**: The horizontal width of the top and bottom flanges of the I-beam is represented by 'b', which is 159 mm. - **d (Overall Depth)**: The vertical distance from the top to the bottom of the I-beam is shown as 'd', which measures 216 mm. - **t (Flange Thickness)**: The thickness of the flanges (the horizontal top and bottom parts of the 'I') is labeled as 't', which is 37.4 mm. 3. **Axes**: - The vertical axis is denoted as the 'y' axis and the horizontal axis is labeled as the 'x' axis. These axes help in defining the orientation and the dimensions of the I-beam. 4. **EC (Elastic Center)**: - The elastic center (EC) is marked along the central web (the vertical part in the middle of the 'I') of the beam. Understanding these dimensions is essential for engineers and architects as they determine the load-bearing capacity and structural integrity of the beams used in construction. In practical applications, choosing the correct dimensions of I-beams is crucial to ensure safety and stability in structures ranging from buildings to bridges. ---
