Elasticity. 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 EA2EB. 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 d for cylinder A and de for cylinder B. (c) What is the ratio d₁/dg? dB com of brick B A
