Is a book bullet proof? How thick must the book be?

Question

General curiousity, in partiucular films where the bible saves the day it being close to the mans heart. I didnt know which category should the question be posted in

Found two links, one link shows a video showing a book that is penetrated by a bullet:

The other tells of a story whereby a soldier is saved from a bullet by a bible:

So its plausible however u look at it i think.

Answer 1

no
Here's why
Force = change in momentum per amount of time
F = p/t; F = (mv(final) - mv(initial))/t
Say the bullet was .002 kg and was shot at the speed of 1000 m/s and the time of impact of the bullet was .1 s.
F = ( .002kg x 0m/s - .002kg x 1000m/s)/.1s
F = 100 N
The diameter of a bullet is about .3in or about .008m
Pressure = Force/Area
P = 100 N / pi(.004m)^2
P = 2000000 Pa
This pressure is about 20 times that of atmospheric pressure and is an immense amount of pressure. A small book would not be able to withstand such pressure.

Perhaps, when you power some thing that is massive and boxy, enormous so that you can add 12-18" of mobile books on the inside and boxy considering that phone books are rectangles and it will be tough to position them on a curved surface. I know that mobilephone books three" or thicker will stop .22LR and birdshot fired inside 25 yards. 6" or more for a volley (10 circular, rapid, grouped intently) of .223 FMJ, and at least 12 for 7.62x39 or larger calibers. But nothing is bullet proof, there's best bullet resistant. If you do not permit the books to broaden as they take on hits, bullets would ultimately (regularly very swiftly) jackhammer away your paper armor. For example, any person that ambushes your automobile is just not more likely to shoot only 30 rounds or less. The vast majority of shootings like that involve at least 5 magazines of anything, which that may go into the 1000's of rounds. As each bullet strikes and prevents, it shreds a good deal of paper, it takes most effective about 20 rounds of .22LR to show a three" telephone book telephone ebook into a publication confetti with a binder. Any variety of cell guide armor would simplest permit you to have ample time to get out of there asap, it turns to confetti far too speedy. It is not just right duvet for greater than 1-three minutes. If you're utilizing that as duvet to preserve yourself, that's now not very lengthy.

It depends on the distance from where the bullet is fired. From a high velocity rifle near by, the bullet may easily pierce through a few hundred pages. A small pistol may fire a bullet with much less velocity and the same may be stopped by a big book.

Also if the bullet strikes the book at an angle, it may either be ricocheted in a new direction or will encounter more path through the paper of the book and thus may be stopped.

Answer 5

It depends on the bullet. A 1/2" book will stop a 32 caliber slug, but a 50 caliber BMG round would go through 2 feet of paper easily. Some bullets fired from a distance will be mostly spent and a lot easier to stop too.

Answer 6

There are many variables. What caliber of weapon. What distance. How thick is the book. For instance, from 30 feet a 400 page book would probably stop a .25 caliber, but it would not stop a .357 magnum.

Answer 7

Lots of things are bullet resistent; nothing is bullet proof! You hide behind something you think will stop the biggest, fastest, hardest bullet your enemy might shoot at you; then your enemy invents a bigger, faster, harder bullet.

Cops wear kevlar vests with cermet plates in the pockets, so the robbers coat their bullets with teflon. Those obsolete Iraqui tanks were made to stop steel bullets, so we fired our nuclear waste at them (which is cheaper than keeping it in safe storage areas---and we call THEM terrorists). Sadam Hussein hid under 200 feet of concrete, so we put a hard nose on an 8-inch naval rifle, filled it with explosives and dropped it from the edge of space.

Answer 8

A book makes a good shield to protect you from a bullet but play it safe and don't try it to prove it. Some bullets are designed to pierce armour, I would think that a book would offer very little protection in that case.

Answer 9

Depend on the bullet caliber, paper type, book thickness, and distance from book. A .50 BMG could pierce any book available.

Answer 10

a .308 round will pentrate 18 inches of solid dirt work it out from there
