In the Figure below, $a=30in,b=37in,L=26in$ and

$P=2\mathrm{.}3$ kips. Determine the downward deflection

af $B$ if $E=31000$ksi and $A=0,03k{n}^2.$ Member ABC is rigid.

$UtNC=U$

$2\mathrm{.}3(6z)+FB(3z)=0$

$37FB=-154\mathrm{.}1$

$FB=-4\mathrm{.}16486$ fips uarr

$f=\frac{4\mathrm{.}16486*26}{0\mathrm{.}0331000}=\frac{108\mathrm{.}28636}{93}$

$=1\mathrm{.}16in$
