Remember that the stiffness and strength of a panel varies with the
*cube* of its thickness.

Stiffness in bending varies with the cube of thickness. Strength is
proportional to the thickness _squared_. For simple cases and for the
sake of rough comparisons, anyway.

Ah, right, Ned. Thanks. I always forget that because I'm almost always
looking at stiffness.

Braggart!
