# Top faces of the cylinders

In the figure, a lead brick rests horizontally on cylindersAandB. The areas of the top faces of the cylinders are related byAA= 1.5AB; the Young’s moduli of the cylinders are related byEA= 1.8EB. The cylinders had identical lengths before the brick was placed on them. What fraction of the brick’s mass is supported(a)by cylinderAand(b)by cylinderB? The horizontal distances between the center of mass of the brick and the centerlines of the cylinders aredAfor cylinderAanddBfor cylinderB.(c)What is the ratiodA/dB?http://d2vlcm61l7u1fs.cloudfront.net/media%2Fd93%2Fd935947d-0086-49c6-85da-d58ff95f9531%2FphpuLCOgM.png
