A $1\mathrm{.}05-$m$-$long rod of negligible weight is supported at its ends by wires A and $B$ of equal length $($the figure $($Figure $1)).$ The cross$-$sectional area of $A$ is $2\mathrm{.}26m{m}^2$ and that of $B$ is $3\mathrm{.}99m{m}^2.$ Young's modulus for wire $A$ is $2\mathrm{.}00{10}^{11}Pa$; that for $B$ is $1\mathrm{.}00{10}^{11}Pa.$

Part A

At what point along the rod should a weight $w$ be suspended to produce equal stresses in A and $B?$ Express your answer in meters.

$d=$ musom wire $A$

Part B

At what point along the rod should a weight $w$ be suspended to produce equal strains in A and $B?$ Express your answer in meters.
