# I'm trying to understand compressive strength and Euler stress for columns

A cloumn has a compressive strength of 220MPa, but its Euler yeild stress is 350MPa. its compressive strength is less than its euler stress.
what does this mean?

That the column will fail due to compression before it can buckle.

The compression strength is the downward forces applied resistances.

so it will fail dowards before it will fail sideways basically?

Thanks
i was getting comfused because both had stress in them so thought it was the same
compressive strength = downward stregth resistance
Euler Stress = sideways to buckling

so by looking at the strength (220) and euler stress (350), it buckles higher than it does when compressing the column.
220 - 350 = 130MPa
is that normal for column?

in the reading material it uses compressive strength as the same value they use for critial stress for the column.

Force aligned with or perpendicular to the main axis of the column could be more accurate terms, since we not always have a vertical column that is supporting a load on top of it.
