特点
1, the hammer is heavy, and dancing is more difficult. Even if there is Samson, and horses are also difficult to withstand.
2, Hammer is short, only melee than guns, long knives, are not taken advantage of.
3, hammer only blunt, far more deadly than guns, long knives and other trauma caused by.
Hammer is knocked the object so that it moves or deformation tools. Most commonly used to knock the nail, correct or object open. Hammer has a wide variety of forms, common form of handle is a handle on the top. Top side is flat to knock, the other side is a hammer. Hammer shaped like horns, can also be a wedge, its function to pull out the nails. Also has a round head shape nails.
When you are using leverage, and labor, power arm longer than the resistance arm levers should be used; if you want distance you should use dynamic resistance than short lever arm in arm. So the lever can be used easily, would save it away. However, to be labor-saving, it must be moved; moving to less distance, there must be some more power. To be labor-saving and less distance traveled, is impossible. It is from these axioms, and the "Centre of gravity" theory, based on Archimedes discovered the principles of leverage, that is, "two weight balance, is inversely proportional to their distance from the pivot and the weight.
Fulcrum doesn't have to be in the Middle, the system that meets the following three points, is basically a lever: Pivot, point of application and the stress points.
Formula wrote: power x power = resistance x resistance arm, that is, F1xl1=F2xl2 is a lever.
?? Power arm extension
lever of the lever there is labor-saving lever effort, both functions behave differently. For example, there is a foot of air compressors, or with a hand press juicer, is labor-saving lever (lever > torque), but we're going down the larger the distance, bearing only small movements. In addition there is a laborious lever. Such as the side of the crane, fishing hooks in the whole tip of the rod, the end is the fulcrum, the middle is the hydraulic press (torque > arm), this is the lever effort, but hard to get to where is the middle of the point of application of force as long as moving small distances, cutting-edge hook will move considerable distances.
Two kinds of leverage are both useful, but where you want to use to assess range of motion is takes less effort or save. There's something called the axle, can also be applied as a lever, however performance may sometimes be combined with rotation calculations.
Ancient Greece scientist Archimedes such a ages saying: "If you give me a place to stand, you can move the Earth" this sentence is not only inspiring aphorisms, is a rigorous scientific basis.
