### Part A **Problem Statement:** Determine the mass moment of inertia of the thin plate about an axis perpendicular to the page and passing through point \(O\). The material has a mass per unit area of \(27 \, \text{kg/m}^2\). (Figure 1) **Instructions:** Express your answer to three significant figures and include the appropriate units. **Input Box:** \[ I_O = \, \text{Value} \, \text{Units} \] **Diagram Explanation:** The provided diagram shows a thin plate consisting of an outer blue circular area and an inner white square section. - The circle has a radius of \(200 \, \text{mm}\). - The square centrally positioned within the circle has a diagonal length equal to the diameter of the circle, which is \(400 \, \text{mm}\). This information is essential for calculations, as the inner square section is subtracted from the outer circular section to determine the actual area contributing to the mass moment of inertia. The axis of rotation passes through the center point \(O\) of the circular plate. ### Additional Notes: Consider converting dimensions from millimeters to meters when performing calculations, as the mass per unit area is given in \(\text{kg/m}^2\). For comprehensive learning in mechanics and dynamics, it is critical to include the principles of mass moment of inertia and the technique of subtracting the moments of inertia of composite areas. This type of problem is typical in structural and mechanical engineering fields.
