Convincing leverage
Before saying convincing leverage.
Let talk what "Lever" first.
According to Wiki :
lever is a simple machine consisting of a beam or rigid rod pivoted at a fixed hinge, or fulcrum. A lever is a rigid body capable of rotating on a point on itself. Use Lever in life can save a lot of energy. It have 3 classical type.
Take the first for example, see the pic below
the heavy object(M1) and the light object(M2) through the short distant(a): long distant(b) get a balance on the fulcrum.
So the first item make Leverage convincing is have a reasonable relationship between the object and the distant form fulcrum.
------
Use the theory, we can apply lever in many thing in our life.
//Take pick up the hammer for example,
The hammer heavy side(M1) to the fulcrum(left hand) is more way short than the right hand(M2) to fulcrum. It make the people earlier to pick up the hammer.
//If in the situation which is pick hammer and put it on your shoulder.
which is mean you make the hammer cross your head and rotate and pull up and put down to your shoulder. It's little bit different than the one above. Because the fulcrum is the hand, the hand connect to the arm and connect to the spine. The spine is holding whole body, and it flexible, so when hammer put up to the top, the force of the spine would change first. If the hammer put down and break the balance of the standing pose(the pic in the middle). spine will give the force to upper right and back to the balance pose(pic on the right), and the timing in the transform also slow how heavy the hammer is.
So the direction of the spine, and how long the timing spend on pick up also are the item of show convincing of leverage.
