Has anyone used the aluminum monopole flagpoles for wind turbines? I am looking at one for 45' and is rated for 107 mph windsHowever, I don't know how this would work with a wind turbine.
This Site Might Help YouRE: can a .32 acp round penetrate a human skull? im thinking bout buying a Tomcat .32acp pistol but can this baby pistol even defend you? i want to start with an inexpensive pistol and easy to manage on the recoil side.i could get several shots off in a short amount of time.but can this round penetrate a human skull or even reach vital.
Yes, a 7.65mm (.32 ACP) projectile will easily penetrate a skullEven a .22 LR will do that7.65mm has a reputation of being used by various government agencies (most notably Mossad) to assassinate dissidents and enemies of the state, usually by dumping a magazine into the back of their headAlthough 7.65mm is thought of today as inadequate it's been used worldwide for over a hundred yearsThe idea that .32 is useless for self-defense is a relatively new opinion, usually voiced by the anything under (insert calibre here) sucks crowdIn my opinion anything that's been effectively used for 100 years can still be effectively used today.
aluminum mono flag poles are only schedule 25 pipe (thickness) to be rated for most wind turbines you'll need a schedule 80 with a oval shape for stabilitydepending on the size and weight of the turbine a tri type of tower or spun aluminum pole is recommended.
Energy is what is required to cause a projectile to penetrate a human skullSimply put, energy is a factor of both the mass (weight) of the projectile and the velocity (speed) at which it is travelingThe .22 long rifle bullet is generally 40 grains (2.6 grams)Depending on the cartridge (.22 short, long rifle, etc., the bullet weight can range from 20 to 60 grainsThe standard long rifle round reaches a maximum velocity of about 1100 feet per second, but certain high velocity or hyper velocity cartridges can increase that number to over 1600 fps and .22 magnum rounds can easily exceed 2000 fpsMaximum velocity is usually attained at approximately 18 from the end of the barrel, thus, that would be the most effective range for the round(However, the round does not lose velocity very quickly, so it's essentially just as effective at any practical close-combat range.) U.SNavy SEALs use the .22 with noise suppressors as effective, quiet ways of neutralizing their targetsFor comparison, a .270 rifle, commonly used for deer hunting, uses a round with a bullet typically weight 130-150 grains and a muzzle velocity of 2800-3200 fpsWith guns, muzzle energy is the amount of energy the bullet has at the point it exits the barrelAgain, this is a factor of the bullet mass and velocityA .22 will have a muzzle energy of 700-1300 (depending on the weight of the bullet and round type and brand)A .270 will have ME of 2700-3300This means that the .270 will deliver 3-4 times the energy of the .22The .22 has enough energy to penetrate the skull and kill a human with a single shotIn comparison, the .270 has much more energy and therefore has a greater likelihood of doing so (almost a surety).
