Question

1. The student looks at the growth rings of the artist’s wood and notes that the widest face of the piece is the tangential surface. The student looks up the maximum tangential shrinkage and fiber saturation point of black walnut in the Wood Handbook online and finds them to be 7.8%, and 23% respectively.

WHAT IS THE MAXIMUM POSSIBLE SHRINKAGE FOR THE ARTIST’S PIECE OF WOOD, ON THE WIDE SURFACE, IF IT IS DRIED FROM ITS CURRENT MOISTURE CONTENT TO ZERO?

2. If the widest dimension of the piece of wood 16.5 cm, HOW MUCH COULD THE WOOD SHRINK, IN CENTIMETERS in the tangential direction, if the piece was dried to zero after carving?
