A W14 x 90 column is made from ASTM A572 Gr. 42 steel and has a length of 16 ft. The column is only supported at its ends. Both ends are pinned. Determine the critical stress, Fcr, for this column, which is also called nominal stress, Fn, in AISC 360-22.

A W10 x 77 column is made from ASTM A572 Gr. 60 steel and has a length of 24 ft. The column is only supported at its ends. Both ends are fixed. Determine the nominal compressive strength, Pn, for this column. Assume the shape is nonslender.

A W10x22 beam made from A992 steel would be classified as _______.

In the ASD equation Pa ≤ Pn /Ωc, the symbol Ωc represents _______.

Select the lightest HP16 column with an effective length of 15 feet that can support a dead load of 160 kips and a live load of 480 kips. Assume Fy = 50 ksi. Use ASD.

Using the column load tables, select the lightest W12-shape with an effective length of 15 ft that will support an LRFD design load of 350 kips.

A W12 x 50 column is made from ASTM A572 Gr. 60 steel and has a length of 28 ft. The column is only supported at its ends. Both ends are pinned. Determine the elastic buckling stress, Fe, for this column.

Use Gaussian elimination to find the complete solution to the system of equations, or state that none exists.x + y + z= 7 x – y + 2z=7 2x + 3z = 14  

Many of the shapes commonly used for columns are slender, and the reduction factor Q will not be needed.

A W8 x 67 column is made from ASTM A572 Gr. 42 steel and has a length of 10 ft. One end is pinned. The other end is fixed against rotation and translation. Determine the effective slenderness ratio.
