Transcribed Image Text:**Problem 7.11**
A thin steel plate, having the dimensions shown, contains three 2-inch diameter holes. Note the axis of symmetry. Locate the centroid of the area.
**Diagram Explanation:**
The diagram illustrates a trapezoidal steel plate with three circular holes, each with a diameter of 2 inches. The dimensions of the trapezoid and holes are as follows:
- The top width of the trapezoid is unspecified.
- The bottom width of the trapezoid is 8 inches.
- The height of the trapezoid is composed of segments: 3 inches at the top, 4 inches in the middle, and 3 inches at the bottom.
- The circles are evenly spaced along the vertical axis of symmetry.
- The distance between the top edge of the trapezoid and the center of the top hole is 3 inches.
- The center of the middle hole is at a central vertical position.
- The center of the bottom hole lies 3 inches above the bottom edge of the trapezoid.
There is a vertical dashed line indicating the axis of symmetry. Each hole is centered along this axis, suggesting symmetrical placement.
