Text in the illustration

floor joist
built-up beam
built-up wood column
note:
the width of a built-up wooden column must be equal to the width of the beam it supports
plumb bob
mason's level
footing
concrete floor slab
gravel
columns may buckle if they are too slender
the taller and more heavily loaded a column is, the more likely it is to buckle
a mason's level or plumb bob can help in identifying and quantifying column buckling or leaning

Generated explanation

The illustration shows a bowed built-up wood column supporting a built-up beam beneath a floor joist. The column rests on a footing below a concrete floor slab with gravel beneath it. A prohibition symbol highlights the column-to-beam connection, accompanied by a note that the built-up column must equal the width of the beam it supports. A mason's level and plumb bob are shown beside the column to illustrate checking for buckling or leaning. Annotations explain that slenderness, height, and heavier loading increase the likelihood of column buckling.
