Explanation Given information: The length of the shaded area is a . The height of the shaded area is h . Calculation: Show the area of the differential element as in Figure 1. Using Figure 1, Express the parabolic value of y . y = h − h a n x n Compute the area of the element. d A = y d x Here, the area of element is dA . Substitute h − h a n x n for y . d A = ( h − h a n x n ) d x Compute the centroid of the differential element along the x axis using the formula. x ˜ = x Determine the location of the center of gravity of the homogeneous rod along the x axis ( x ¯ ) using the relation. x ¯ = ∫ A x ˜ d A ∫ A d A (1) Conclusion: Substitute x for x ˜ and ( h − h a n x n ) d x for dA in Equation (1). x ¯ = ∫ A ( x ) ( h − h a n x n ) d x ∫ A ( h − h a n x n ) d x (2) Apply the limits from 0 to a in Equation (2) and calculate the numerator part
