The $C83400$ red$-$brass rod $AB$ and $2014-$T$6$ aluminum rod $BC$ are joined at the collar $B$ and fixed connected at their ends as shown in $($Figure $1).$ The cross$-$sectional area of each member is $1\mathrm{.}75i{n}^2.$

If there is no load in the members when $T_1=50F,$ determine the average normal stress in the member $AB$ when $T_2=105F.$

Express your answer in kilopounds per square inch to three significant figures.
