o D. The mass is not exactly 255.0 grams, but it is impossible to tell whether the mass is greater than or less than 255.0 grams. 5. 5. You place a mass of 250 grams on the measurement tray of a triple beam balance and then set the rider on the 500 gram beam to the 200 gram mark (the other riders are set to 0 grams). Which of the following statements is true?
(2) Burster-type white phosphorus. White phosphorus projectiles are available for 105-mm and 155-mm howitzers. They are bursting-tube type projectiles that can be fired with point-detonating (PD) or MTSQ fuzes. The projectile has an incendiary-producing effect and is ballistically similar to the HE projectile. Normally, shell WP is employed for its incendiary effect.
F – The M107 projectile is the only HE round authorized by the US Army 5. T – The scavenge isolation valve should be in the close position during breech maintenance 6. F – If the COS is not under the net and a fire mission is received the gunner can shoot the mission as long as he verifies the data on the CSD 7. F – The dog coupler and PFM lever must be present and operational in order to fire the howitzer 8. T – During a high angle multiple round fire mission the tube must be depressed to 800 mils between each round fired 9.
M249 Light Machine Gun The M249 light machine gun is a gasoperated, aircooled, belt or magazinefed, automatic weapon that fires from the openbolt position firing the M855 ball 5.56x45mm round and the M856 tracer variant. It is an adaptation of the FN Minimi, a Belgian made machine gun; used by the United States military. It has a quick change barrel that can be changed in case of a damaged or overheated barrel, is equipped with a folding bipod but can be attached to a tripod for greater stability when firing. It can be fed by either linked rounds or magazines, this way the operator can use magazines from nearby riflemen in case they run out of ammunition. The M249 saw was adopted by the U.S. Army in the 1980’s to provide a mobile equivalent to the M240B heavy machine gun and the M60 medium machine gun.
In the first trial , we shot the circular metal ball out of the gun at an angle parallel to the ground(0).The gun , itself , had three levels of compression . The third compression was the strongest and thus , shot the ball farthest , and the first compression performed the weakest force. First , the value of time was calculated using the formula: t √2yo/g.Yo was set equal to 1, illustrating that the gun was positioned 1m from the ground, and g was equal to 9.8 (gravity constant). With this information, our time was found to be .45175 seconds. Now , using the plastic rod , we positioned the gun to its third compression and shot the ball a total of 3 times .Using a meter stick , we measured the
From this stance you can step out with your lead leg or back with the rear in order to transition to a fighting stance. The shooting stance is a little different because there are 3 different styles the Weaver, Isosceles, or Weaverese which is a combination of Weaver and Isosceles. The Three-In-One-Stance was created by the author of this article, Amaury Murgado. This stance uses the body’s natural movements and stance to make it more comfortable to the officer. Naturally a person’s feet are around shoulder width apart and parallel to each other, Amaury decided that if you take a half-step back with your gun leg, bend your knees slightly and bring your hands up to the middle of your chest that it will be more comfortable and easier to transition into either a fighting stance or a shooting stance.
A 2006 test was made by Matheus Bane using a 75 lbf (330 N) draw (at 28") bow, shooting at 10 yards; according to Bane's calculations, this would be approximately equivalent to a 110 lbf (490 N) bow at 250 yards.  Measured against a replica of the thinnest contemporary "Jack coat" armour, a 905 grain needle bodkin and a 935 grain curved broadhead penetrated over 3.5 inches (89 mm). ("Jack coat" armour could be up to twice as thick as the coat tested; in Bane's opinion such a thick coat would have stopped bodkin arrows but not the cutting force of broadhead arrows.) Against "high quality riveted maille", the needle bodkin and curved broadhead penetrated 2.8". Against a coat of plates, the needle bodkin achieved 0.3" penetration.
Some who favor treatment-based model of supervision have objected to officers carrying a firearm, while others have embraced it. Some agencies throughout the United States have made carrying a weapon an option, some others have gone the mandatory route, while others still do not allow their officers to carry at all. Probation and parole officers experience violent incidents including verbal threats, attacks by offenders' dogs, bomb threats, physical assaults, and resisting arrest. Some argue that probation and parole agencies should authorize their officers to carry firearms in response to these challenges. Parole officers are supervising a violent offender population and are being asked to participate in more aggressive activities.
Running Head: Tasers and Impact Munitions Tasers and Impact Munitions Jana Engleking Everest University CCJ 1020-12 Professor Demetric Armstead March 12, 2012 Tasers and other stun guns have proved effective in limiting injuries to police and suspects, but law enforcements need to guard against potential abuse by officers who overly rely on such tools (The Post and Courier, 2009). The findings from a study are included in one of the largest studies conducted into police use of force and injuries that result from stun guns, pepper spray, batons, and firearms (The Post and Courier, 2009). The study, funded by a $650,000 U.S. Justice Department grant, comes at a time when more than 11,500 police agencies use Tasers to control suspects
