being able to fire a projectile to a distance of up to three hundred yards accurately. It consists of a lever arm laid across a supporting crossbeam (the fulcrum)‚ a heavy counterweight on one end‚ and a sling on the other. The sling would hold the load (projectile) during battle and eject it on operation of the lever arm. The weight end is usually about a fourth of the length of the resistance end‚ as the counterweight would be more than four times heavier than the projectile for maximum accuracy

continuum may advise that the next level of force be used‚ in many cases‚ pepper spray (Pearson‚ 2003). If the subject is wielding a firearm‚ lethal force may then be used. Law enforcement has long recognized that a wide and dangerous gap exists in the range of tools available to them. The only tools traditionally available‚ baton or gun‚ may be either too weak or too strong a response to some situations. This fact became clear after the Supreme Court ruled in Tennessee v. Garner that the use of deadly

generation of police officers‚ community and problem-oriented policing have been advanced by their advocates as powerful organizing themes for an emergent style of public safety. How these themes have impacted American policing is yet uncertain. The range and complexity of programs associated with community and problem-oriented policing have often precluded systematic scientific investigation. Moreover‚ community and problem-oriented policing are themselves “moving targets”—changing and modifying themselves

The larger‚ heavier catapult could throw stones up to 60 pounds. The mechanism that propelled the projectile was usually tightly twisted animal sinew or human hair and had a range of about 450 meters with an eight pound projectile.

dependent on men and firepower‚ so the side with the best guns would come to victory. The French military had a range of modern weapons. For example‚ they armed their men with the ‘Chassepot’‚ a modern rifle which was much more powerful than the Prussian Gun. The Chassepot (named after its creator) was a large evolution from the Minié rifle. It was bolt-action and had a firing range of about 1.2km. It could fire about 8-15 rounds a second‚ unlike the Minié which fire about 2-3 shots per minute.

These factors are particularly important to performance of the shot put and discus but there are many other important factors that also contribute‚ including range of motion‚ timing‚ position‚ internal force‚ and external force. The next area that we are going to look at is speed. Results from studies done by M. Hubbard et al. showed that Achievable release speed decreases with increasing release angle at
