March 28, 2008 PHY2053 Discussion Quiz 8 (Chapter 8.1-8.5) Name:                                   UFID: *1. (5 pts) A 4.00 ft by 8.00 ft uniform rectangular sheet of plywood is located so that x-  and y- coordinates of the four vertices are (4.00, 2.00) ft, (-4.00, 2.00) ft, (-4.00, -2.00) ft  and (4.00, -2.00) ft. Now suppose the upper right quadrant is removed from the sheet  and find the center of the gravity of the remaining sheet.  We consider the sheet consisting of two parts: One is a 4 ft by 4 ft square in the 2 nd  and  3 rd  quadrants, the other one is a 4 ft by 2 ft rectangle in the 4 th  quadrant. Their centers of  gravity are located at (-2, 0) ft and (2, -1) ft respectively. The 4 × 4 square is twice as  heavy as 4 × 2 rectangle. Thus the center of the gravity of the remaining sheet is located
