Aerodynamics not only affect the trajectory curve but also influence the striking velocity
. This translates directly to bullet energy, a formula that uses the square of velocity.
Calibers, mass, velocities (including muzzle velocity and striking velocity
), and energy of projectiles and mean values of DOP data obtained from experiment and numerical simulations are listed in Table 2.
According to a nonlinear hysteretic piano hammer model and in reality , the duration of contact between the hammer and the string decreases with the increasing of the striking velocity
of the hammer.
The projectile bar is accelerated by the use of air pressure, and the projectile striking velocity
is measured by laser velocimeter with the light distance of 0.1 m.
The range of the impactor mass and the striking velocity
were, respectively, from 1 T to 50 T and from 5 m/s to 400 m/s.
One problem with lead-free bullets in general is that while they do expand nicely under some (skeptics might say perfect) conditions, they are quite fussy about the striking velocity
that provides the very best performance.
Helmer's steady hand, including astute use of CGI, keeps things moving with striking velocity
. A chase/fight sequence in the pic's midsection is a showstopper.
This paper addresses the wounding potential and power of a soft-nose bullet at the striking velocity
and the remaining velocity when fired through glass of various thicknesses.
Because the striking velocity
was at about 30 mph and the change in velocity was about 43 mph, this indicates that the subject vehicle was pushed backward at about 13 mph after the accident with the other, larger vehicle.
The liquid lubricant and bore conditioner already has a lot of good press, mostly from handloaders who claim some pretty striking velocity
[V.sub.s] = the striking velocity
of the projectile [V.sub.12] = the velocity at the midpoint between screens 1&2 S1= the distance from midpoint between screens 1&2 and the target C = correction constant, 52.4 m [V.sub.r] = the residual velocity after penetration [V.sub.34] = the velocity at the midpoint between screens 3&4 S2= the distance from midpoint between screens 3&4 and the target.
Similar negative effects can be caused by incorrect rotation or the wrong striking velocity
in the piston.
