The practical maximum length to diameter ratio in current long rod projectiles   
   is typically thought of as somewhere between 30:1 and 40:1. If you were to   
   scale up the projectile several times, could the long rod maintain the same   
   aspect ratio?   
      
   e.g. If you had a 75cm length/2.5cm diameter long rod and scaled it up 10x to   
   750cm/25cm, could it be expected to maintain the same degree of rigidity   
   during acceleration, flight, and impact?   
      
   The "Rods from God" concept envisioned tungsten rods of 6.1m length and 0.3m   
   diameter, so at the very least they thought that a 20:1 aspect ratio was   
   possible at that scale.
