Approximate the curve shown using 10 straight-line segments, and then write a computer program that can be used to determine the location of the centroid of the curve. Use this program to determine the location of the centroid when (a) a = 1 in., L = 11 in., h = 2 in.; (b) a = 2 in., L = 17 in., h = 4 in.; (c) a = 5 in., L = 12 in., h = 1 in.
