Janka developed a scale to measure how easy it is to dent wood used for construction.
It measures the force required to embed an 11.28-millimeter-diameter (7?16 in) steel ball halfway into a sample of wood. (The diameter was chosen to produce a circle with an area of 100 square millimeters, or one square centimeter.)
