Having a hard time understanding how to solve these using the Area, Mx and My technique
5. Find the centroids C= (x, y) for the following regions. Take advantage of symmetry whenever you can. a) The region bounded from above by the semi-circle y = 4x-x, 0 x 4 and below by the x-axis. Comment: The radius of this semi-circle is r= 2 . b) The region bounded from above by the curve y = 2 cosx, Sr / 2 and below by the x-axis. The infinite region bounded from above by the curve y = x2c", x 20 and below by the x-axis. Is the centroid inside or outside this region? Why? Note that:(x'e"")xe d) The region bounded from above by the curve y= 2 sin x, 0 St Sr and below by the line y =-1 . e) The infinite region bounded from above by the curve y = xe-n x 20 and below b the x-axis. Is the centroid inside or outside this region? Why?
