Problem 1(10 points) Select the lightest-weight wide-flange beam from booklet, that will safely support the loadin shown. The allowable bending stress
\sigma _(allow )=22ksil
and the allowable shear stress of
\tau _(allow )=12ksi
. Problem 2 (10 points) A distributed load of
10ki(p)/(f)t
is applied on a beam. If the allowable bending stress
\sigma _(allow )=24ksil
and the allowable shear stress of
\tau _(allow )=14ksi
, select the lightest wide-flange section with the shortest depth from booklet, that will safely support the loaa.
