Solution Steps

Step 1: Understanding the Moment of Inertia

The moment of inertia of an area with respect to an axis is a measure of how the area is distributed relative to that axis. For the xx axis, it involves the distribution of the area in the yy direction.

Step 2: Identifying the Correct Formula

The moment of inertia IxI_x with respect to the xx axis is given by the integral of y2y^2 times the differential area dAdA. This is because the distance from the xx axis to a point in the area is given by the yy coordinate.

Step 3: Selecting the Correct Option

Among the given options, the correct formula for the moment of inertia IxI_x with respect to the xx axis is: Ix=y2dA I_{x} = \int y^{2} \, dA

Final Answer

Ix=y2dA \boxed{I_{x} = \int y^{2} \, dA}
