Problem $1)$ The rigid beam shown is supported by a $\frac{3}{4}"$ diameter aluminum cable at the left end and a $\frac{1}{2^{\text{'}\text{'}}}$ diameter copper cable at the right end. Determine the deflection in each cable after a $1500$ lb load is applied $($as shown$).$

$E_A=11,000$ksi

$E_C=18,000$ksi

$A_{AL}=\frac{(\frac{3}{(4{)}^{\text{'}\text{'}}}{)}^2}{4}=$

$A_{CB}=\frac{(\frac{1}{(2{)}^{\text{'}\text{'}}}{)}^2}{4}=$

$\frac{O}{{?}_{AL}}=\frac{3}{4}$

$\frac{O}{{?}_{cp}}=\frac{1}{2}$

zeta$=\frac{R_{AL}^{\text{d}\text{a}\text{r}\text{r}}{L}^7}{AE}$

$P=150016$
