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 \(A_A = 1.6 \, A_B\); the Young's moduli of the cylinders are related by \(E_A = 1.6 \, E_B\). 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 \(d_A\) for cylinder A and \(d_B\) for cylinder B. (c) What is the ratio \(d_A/d_B\)?

Diagram Explanation:
The diagram shows a lead brick resting on two cylinders labeled A and B. The brick is placed such that the horizontal distance from the brick's center of mass (com) to cylinder A is \(d_A\), and the distance to cylinder B is \(d_B\).

For the calculations, the answers for the fractions and ratio can be entered in the boxes provided: 

(a) Number (fraction of mass supported by cylinder A) and Units.

(b) Number (fraction of mass supported by cylinder B) and Units.

(c) Number (ratio \(d_A/d_B\)) and Units.
