In the figure, a lead brick rests horizontally on cylinders A and B. The areas of the top faces of the cylinders are related by AA- 1.6 Ag; the Young's moduli of the cylinders are related by EA- 2.3 Eg. The cylinders had identical lengths before the bric was placed on them. What fraction of the brick's mass is supported (a) by cylinder A and (b) by cylinder B? The horizontal distances between the center of mass of the brick and the centerlines of the cylinders are dafor cylinder A and dg for cylinder B. (c) What is the ratio da/dg?
