I used a 2ft. piece of 2x12 Doug Fir as a small ramp for truck.
When truck weight was on the 2x12; the 2x12 flexed (sagged) a little and when the weight was removed the 2x12 went back into its regular straightness.
The wood made a little popping sounds but there are no cracks or anything.
I’m curious as to is this wood still strong in both planes or did the momentary sagging under weight greatly reduce the strength of the the wood?
