Problem 7.9yy = kx 1/3aLocate the centroid of the volumeobtained by rotating the shaded areaabout the x axis.hx46
yy = kx 1/3haxSolving Problems on Your OwnLocate the centroid of the volumeobtained by rotating the shaded areaabout the x axis.The procedure for locating thecentroids of volumes by directintegration can be simplified:Problem 7.91. When possible, use symmetry to help locate the centroid.2. If possible, identify an element of volume dV which producesa single or double integral, which are easier to compute.3. After setting up an expression for dV, integrate and determinethe centroid.47
