Select the lightest W shape $($in SI designation$)$ for a column subjected to an

axial compressive load of $1500$ kN$.$ The column has an unbraced length of

$12$ m and is fixed at both ends. Assume that the column is made of A$441$

steel with a$,=345$ MPa. Use the AISC specification and the allowable stress

listed in Table $19-3.$

Select the lightest W shape for a column subjected to an axial compressive

load of $200$ kips. The column has an unbraced length of $30$ ft and is fixed at

both ends. Assume that the column is made of A$441$ steel with a$,=50$ ksi. Use

the AISC specification and the allowable stress listed in Table $19-3.$

Select the lightest W shape for a column subjected to an axial compressive

load of $500$ kips. The column has an unbraced length of $40$ ft and is fixed at

both ends. Assume that the column is made of A$242$ steel with o$,=50$ ksi. Use

the AISC specification and the allowable stress listed in Table $19-3.$

Select the lightest standard weight steel pipe section $($in SI designation$)$ to

support an axial compressive load of $700$ kN$.$ The column has an unbraced

length of $10$ m and fixed, pinned ends. Assume that the column is made of

A$36$ steel with o$,=250$ MPa. Use the AISC specification and the allowable

stress listed in Table $19-2.$

Select the lightest standard weight steel pipe section to support an axial

compressive load of $80$ kips. The column has an unbraced length of $20$ ft

and is pinned at both ends. Assume that the column is made of A$242$ steel

with o$,=50$ ksi. Use the AISC specification and the allowable stress listed

in Table $19-3.$
