In Figure a lead brick rests horizontally on cylinders A and B. The areas of the top faces of the cylinders are related by AA = 2AB; the Young??s moduli of the cylinders are related by EA = 2EB. The cylinders had identical lengths before the brick 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 dA for cylinder A and dB for cylinder B.

(c) What is the ratio dA/dB?
