Morning NG — let's get this done. Step 1: Calculate the moment of each component about the line AB. The moment of each component is its weight multiplied by the distance of its centroid from AB. For triangle ADE: Moment_1 = (sqrt(3)2 W) × (sqrt(3)3) = (3)/(6) W = (1)/(2) W For rectangle EFCD: Moment_2 = (2sqrt(3) W) × (sqrt(3)2) = (2 × 3)/(2) W = 3 W For triangle F1CB: Moment_3 = (sqrt(3)2 W) × (sqrt(3)3) = (3)/(6) W = (1)/(2) W Step 2: Calculate the total moment about AB. Total Moment = Moment_1 + Moment_2 + Moment_3 Total Moment = (1)/(2) W + 3 W + (1)/(2) W = 4 W Step 3: Calculate the y-coordinate of the centroid (y) for the entire lamina. The y-coordinate of the centroid is the total moment divided by the total weight of the lamina. The total weight of the lamina is given in your table as 3sqrt(3) W. y = Total MomentTotal Weight = (4 W)/(3sqrt(3) W) Cancel out W: y = (4)/(3sqrt(3)) Rationalize the denominator: y = (4)/(3sqrt(3)) × sqrt(3)sqrt(3) = 4sqrt(3)3 × 3 = 4sqrt(3)9 The y-coordinate of the centroid from AB is 4sqrt(3)9 m. The final answer is 4sqrt(3)9 m. Send me the next one 📸
