Problem $5\mathrm{.}5.$D $($from text$)$

A simple span beam, made up of Hem Fir No$.1$ grade$)$ supports a uniformly distributed load of

$12$ kips.

a$)$ Compute the shear force $(V).$

b$)$ Using the force computed in part a$,$ and the allowable shear force parallel to grain $(f_v)$

shown in the tables in Chapter $5,$ compute the required cross sectional area.

c$)$ Use the area from part b $($and Table A$\mathrm{.}8)$ to determine the required nominal cross$-$

sectional dimensions of the beam. Assume the beam will have a nominal width of $8"($i$.$e$.$
