In order to obtain quantitative measurements of force, penetration, and energy delivered by rod impact, 25.4-mm-diameter steel rods of lengths of 3.66 m (12 ft), 12.19 m (40 ft), and 23.74 m (77.9 ft) were supported horizontally and struck at one end with a reproducible hammer blow. Force, penetration, and energy values were determined from the measured penetration into a standard material (Oasis floral foam). The data obtained indicate that rod length is a significant factor with respect to penetration and energy delivered.
