A 10 foot long 2×4 carrying a uniform load of 40 pounds per foot (400 lbs total load) will have a maximum bending moment at the center of the span of 1000 ft-lbs. The same 10 foot long 2×4 with a point load of 400 lbs at the center will experience a maximum bending moment of 500 ft-lbs.

## How much weight can an inch of wood hold?

## Is a 2×4 stronger on its side?

Thus, we can simply divide these two areas to get the ratio of a 2×4’s stiffness in each orientation. The Ls cancel out, leaving us with just 3.5/1.5 = 2.333. Or in other words, a 2×4 on its side is 2.333 times stiffer than one on edge.
