Problem $6.($Topic Area #$1,4)$

$--$Determine external reactions and internal pin force.

$--$Draw shear & moment diagrams for full beam.

$--$Indicate x$-$location and magnitude of max compression and tension flexural stresses in the left $15$ feet of the beam $(x=0$ to $15$ feet$).$

Note: Same beam cross$-$section as Problem $1.$

$x$

$x=5ft$ from left end of beam

$f_{b,\text{m}\text{a}\text{x}}(c)=-9\mathrm{.}3$ksi $($top of beam$)$

$f_{b,\text{m}\text{a}\text{x}}(T)=6\mathrm{.}19$ksi $($bottom of beam$)$
