Description

There is the leverage of positioning element
Technical field
The utility model relates to a kind of leverage with positioning element.
Background technology
Lever is a kind of simple machine.The object that can rotate around attachment point is under force exactly lever (lever). and lever is not necessarily straight, also can be bending, but must ensure that the lever in physics book is object.Seesaw, scissors, spanner, crow bar, fishing rod etc. are all levers.Pulley is a kind of lever of distortion, and the essence of fixed pulley is bascule, and the essence of movable pulley is laborsaving lever.In junior physics, the solid object that can be rotated around attachment point is under force called lever.Archimedes proposes lever principle the earliest in " balance of opinion planar graph " book.First he be used as some experimental knowledgees in lever practical application " self evident axiom ", then from these axioms, uses geom by tight logical argumentation, drawn lever principle.These axioms are: (1) hang up equal weight at the two ends of weightless bar from the distance that fulcrum is equal, and they will balance; (2) hang up unequal weight at the two ends of weightless bar from the distance that fulcrum is equal, heavy one end will have a down dip; (3) hang up equal weight at the two ends of weightless bar from the unequal distance of fulcrum, one end of distance will have a down dip; A weight effect can with several well-distributed weight be used for replace, as long as the position of center of gravity remains unchanged.On the contrary, the weight that several well-distributed weight can be suspended on their center of gravity place with replaces; Center of gravity like figure distributes in a similar manner ... just from these axioms, on the basis that " center of gravity " is theoretical, Archimedes has found again lever principle, namely, and " during two weight balances, they are inversely proportional to from the distance of fulcrum and weight.The essential element related in lever has " power, resistance, power arm, resistance arm and fulcrum.1. fulcrum: lever, around the attachment point rotated, represents with O usually.2. power: for achieving the goal and making the power of lever rotation, usually represent with F.3. resistance: the power hindering lever rotation, represents with F usually.4. power arm: from fulcrum to the distance of dynamic action line power arm, usually represent with L.5. resistance arm: from fulcrum to the distance of drag effect line resistance arm, usually represent with L.Note: the static or uniform rotation of lever, just says that now lever is in state of equilibrium.But in our every day use process, find some shortcomings part: as, existing structure comparison is single, and function is fairly simple; For another example, present people not only pay attention to its practicality and also pay attention to that it is attractive in appearance; When we study lever principle at ordinary times; I can use lever usually; general lever comprises first type surface symmetry can graduated chi body and counterweight; chi body bilateral symmetry is provided with balance adjustments parts, and Chi Ti center has been rotatably connected S. A., but in our use procedure; find a problem; be exactly that lever can only be put in the horizontal plane, if when needing to show many people to observe, sight line is easily stopped.Also have a problem to be carrying out in experimentation, lever due to the change of center of gravity, can have influence on the result of experiment when hanging counterweight.
