Locate the centroid of the shaded area enclosed by the curve y2 = ax and the straight line shown in Fig. P-726. Hint: Observe that the curve y2 = ax relative to the y-axis is of the form y = kx2 with respect to the x-axis.
Locate the centroid of the shaded area shown in Fig. P-718.
Determine the coordinates of the centroid of the area shown in Fig. P-715 with respect to the given axes.
The dimensions of the T-section of a cast-iron beam are shown in Fig. P-714. How far is the centroid of the area above the base?
