## Summary:

- The ultimate compressive strength of two 2*4s bound together (say screwed together securely) is greater than one 4*4. Why is this the case?

The answer learned in class is that the two 2*4s are able to distribute the load over both of them, but I don't think this is an actual answer because that's balanced by the fact that each block is half the area. Does anyone know of the reason for this observation? Thanks!
