Transcribed Image Text:**Problem Statement**
Find the centroid of the following cross-sections and planes.
**Diagram Explanation**
The diagram provided is a structural cross-section resembling an inverted "U" shape, which is often used in engineering and architectural contexts. The cross-section is dimensioned as follows:
- The overall width of the top horizontal section is 10 inches.
- The height of the top horizontal section is 2 inches.
- Each of the vertical sections (legs of the inverted "U") is 8 inches tall.
- The width of the vertical sections is 2 inches each.
- The gap between the vertical sections (inner width of the "U") is 6 inches (calculated from 10 inches total width minus 2 inches width for each vertical section).
**Reference Origin**
The origin for reference (R.F.) is marked at the bottom-left corner of the structure.
**Task**
Use the given dimensions to calculate the centroid of the structure, which is the point that represents the geometric center of the cross-section. This can involve dividing the structure into standard geometric shapes, finding their individual centroids, and then using the principle of moments to determine the overall centroid location.
