To set up the integral for the area moment of inertia about the y-axis (Iy) using a vertical strip, express the differential area dA as the product of the strip's height (upper boundary minus lower boundary) and its width dx. Substitute this into the definition Iy=∫x2dA and determine the integration limits based on the horizontal extent of the region bounded by functions of x.
Conditions: The region is bounded by curves that can be expressed as functions of x.; A vertical differential strip is chosen, meaning its width is dx.; The integration variable is x.
