Match the integrand with the quantity the double integral then gives. 1. \( 1 \) 2. \( x \) 3. \( x^{2} \) P. First moment about the \( y \)-axis Q. Area of the region R. Second moment about the \( y \)-axis
Answer: A
An integrand of one accumulates area. Weighting by the distance \( x \) gives a first moment, from which the centroid follows on dividing by the area. Weighting by the square gives a second moment, the quantity that appears in bending and in moments of inertia
