What causes the penetrating power of a bow & arrow?

Question

OK a arrow passes through deer size game to the extent that you quite often lose an arrow not common knowlage but they penetrate bullet p vest any other factors besides weight the fastest one i have is only 235 ft my recurves are212 to218 but they penetrate more than mag firearms do. Hey give me a break it 5:30 AM and im bored just thought i would ask

I better watch asking questions half asleep im have to lrt you guys choose the best answer they are all good answers i dont to pick one Thanks Johnny

Answer 1

If you stop to consider most hunting bullet are some what of a blunt design, and are designed to expand on impact to transfer bullet energy in to knock down power.
Once at full expansion a bullet can double or even triple its original diameter, all the while increasing drag to an exponential point.

Where as a hunting arrow for deer is just the opposite, the arrow point is razor sharp and designed not to expand what so ever there by all energy is used in penetration not knock down.
Even on expandable designed hunting tips, only razor sharp blades expand out and offer little resistance to penetration.

Where as if you compared a bullet that is designed not to expand on impact, but retain its original shape up on impact.
The end result would be all most no energy transferred to knock down and increased penetration potential.
If you compared that to an arrow of a blunter design like a Dumb Dumb used on rabbits and bird hunting, the arrows energy is used in knock down power and not penetration.
It all boils down to design function.
Hope this was of some help.

Answer 2

Ballistically the .38 (assuming .38 spl) is more beneficial effective than the searching bow, yet at the same time is way less acceptable for searching. you may not in any respect want to seek deer with a .38, yet all way of massive sport is taken many times, and has been for millenia, with the bow and arrow. edit: an arrow is heavily heavier than a bullet, in spite of the undeniable fact that the bullet is going a lot speedier, and power is calculated depending on the sq. of the speed of the projectile. case in point, a compound bow able to sending a 350-grain arrow three hundred fps will in undemanding words provide seventy 5 feet. lbs. of power, while a 158 grain .38 spl (non +p) semi wadcutter bullet vacationing at 755 fps will produce 2 hundred feet. lbs. of power.

Answer 3

The second answer is correct. An arrow can do a major amount of damage and cause major blood loss. The force is concentrated in a narrow point which breaks the skin or armor and then the sharp points of a broadhead rip the skin apart as they enter and exit.

If you shoot a bucket full of sand, it will stop some small bullets, but a broadhead will penetrate.

Answer 4

The penetration of an arrow is determined by its kinetic energy minus the resistance to penetration. Kinetic energy is easily determined by multiplying one half the mass of the arrow by the square of its velocity. Resistance to penetration is a bit harder to determine. It consists of the sharpness of the arrow point and i ts friction as it enters the target medium. Obviously, a blunt point arrow will penetrate a shorter distance than a sharp pointed arrow. Friction of the arrow in the target medium is what keeps an arrow from going all the way through a target or exiting with the same velocity as it entered. One could try to quantify the resistance to penetration using an accurate scale to determined how much pressure is needed to press an arrow into a target medium to a predetermined depth. Subtract this number from the kinetic energy that you determined above to come up with a penetration factor. This factor can be used to compare the relative penetration of different arrows when fired from the same bow. Hope this helps.

Answer 5

Besides being heavier than a bullet, an arrow also has a sharp point. Even though a bullet travels much faster, the arrow's energy is all focused on the small point when it hits the target.

Think of it in terms of pressure. 10 pounds of pressure on a 1 square inch area is 10 psi. But 10 pounds of pressure on a 0.01 square inch area is 1000 psi.

Answer 6

Hunting bullets are designed to break up, if you shot an Armor Piercing round at the deer, it would come out the other side undeformed in the least.

Answer 7

A bullet is designed to shatter and cause massive tissue damage. An arrow basically pokes a hole. If it does not hit anything vital, it does minimal damage.

Answer 8

The penetrating power is caused by the velocity of which it's fired, similar to a gun.
