base and free in rotation and translation at the top?

$0\mathrm{.}5$

$0\mathrm{.}7$

$1\mathrm{.}0$

$2\mathrm{.}0$ Choose the lightest weight steel column for a column with $KL=18ft$ and a load on the

column $=245$kips

HSS $99\frac{1}{4}$

HSS $99\frac{5}{16}$

HSS $99\frac{3}{8}$

HSS $99\frac{1}{2}$

HSS $99\frac{5}{8}$ Choose the lightest weight wood column for a column with $KL=12ft$ and a load on the

column $=155$ kipsTruss elements can experience which types of stress?

shear

tension

compression

bendingA $20$ foot tall HSS $66\frac{1}{4}$ steel column has a required column load of $60$ kips.

Is the column capacity adequate for the required load?

Yes, the column is $OK$ for the required load

No$,$ the column is NOT OK for the required load
