What is Destructive power of bullet is determined by: and explain in detail?
Velocity of bullet Repeat from May 09 Mechanics of Bullet Injury A bullet's ability to produce tissue injury depends on: Bullet velocity- A bullet's ability to injure is directly related to its kinetic energy at the moment of impact. Kinetic energy i.e. E = me /2 The kinetic energy is directly propoional to weight (mass) of the bullet and the square of its velocity. Thus a bullet traveling at twice the speed of a second bullet of equal weight and similar size and shape, possesses four times much energy and injuring power. Tissue density- The greater the tissue density, the greater is the amount of energy discharged by the bullet passing through it and thus greater the injury. Thus a bullet may cause slight damage to the soft tissue, but extensive damage to hard tissue such as bone. Hydrostatic force- Hydrostatic forces increase the impact of injury. When fluid distended hollow organs, (e.g. urine filled bladder, filled stomach, hea filled with blood in diastole) are hit by a bullet, extensive lacerations are produced due to the explosive displacement of the liquid in all directions.
