An arc along the length of a board is called which term?

Explanation:
The main idea here is understanding how lumber can warp or cup along a board. When the board shows a gentle, arc-like curvature running along its length, this is described as crown. In practice, crown refers to that single-arc deformation along the length, which is different from a curl (twisting or curling action), a wave (multiple bends along the length), or a bend (a more general and less specific curvature). So the arc along the length is called crown.
