Given: A $4"$x $8^{\text{'}\text{'}}$ timber beam spans $14$ feet and carries

a total uniformily distributed load of $60l\frac{b}{f}t$

Compute the shear stress $($Fv$)$

Hint: you can use the simple formula $($slide $27$ lesson

since it has a rectangular cross section

$fv=24\mathrm{.}8$psi

$fv=19\mathrm{.}7$psi

$fv=3\mathrm{.}5$psi

$fv=16\mathrm{.}6$ psi
