Sometimes column size can be governed by the crushing perp to grain, unless you don't mind interrupting the sill plate. Sometimes, I'll use a 6x8 post over a 3 1/2 x 3 1/2 PSL, but it depends on the project. I don't ever ignore it and it can be serious problems in boundary members of shear walls in 4 or 5 story wood buildings.

Material trapped between a solid plate and a rotating roll is shorn by its contact with the teeth on the roll. Often the sheer crushing is combined with other crushing methods, such as compression, attrition, and impact, for mineral size reduction. For example, single roll crushers employ shear together with impact and compression.
