Probability of bullet penetration increases as the axis of bullet movement becomes perpendicular to the target surface; but penetration may create a depression or crater within which the bullet may ricochet more than once, possibly following the arc of the crater floor to depart the crater at a greater angle from the original surface than the ...
Prince Rupert's drops have remained a scientific curiosity for nearly 400 years due to two unusual mechanical properties: [4] when the tail is snipped, the drop disintegrates explosively into powder, whereas the bulbous head can withstand compressive forces of up to 664,300 newtons (67,740 kg f).
Bullet parts: 1 metal jacket, 2 lead core, 3 steel penetrator. Terminal ballistics is a sub-field of ballistics concerned with the behavior and effects of a projectile when it hits and transfers its energy to a target.
