Levers - Coggle Diagram
Levers
Different classes of levers
First Class Levers
the fulcrum is in the middle of the effort and the load.
second class lever
In second class levers the load is between the effort (force) and the fulcrum.
Third class lever
The third-class lever differs from the second-class lever in that the distribution of forces is changed in relation to the fulcrum
Lever systems in the body
The lever in the body is a type of movement made by the bones to make a hard movement easier, working literally like a lever, for example to pull something that is heavy or to throw farther away something.
The system is composed by four components
THE LOAD
THE FULCRUM
THE EFFROT
THE LEVER
Mechanical advantages and disadvantages
Advantages
Move heavier loads, being able to pull this objecs further on.
In a lever, if the distance from the effort to the fulcrum is longer than the distance from the load to the fulcrum, this gives a greater mechanical advantage.
Levers are used to multiply force, In other words, using a lever gives you greater force or power than the effort you put in.
Disadvantages
If the greater force is needed to be applied than the load to be moved its proved that this will became a disadvantage of the lever system.
Over time, the weight and movement causes wear near the fulcrum point, leading to bending and eventual breaking.
Planes of motion
Sagital plane
Frontal Plane
Transverse Plane
The major body axes
For the body to move there has to be a joint, there are three different body axes, depending on the movement made a different axis is inflceted, and that specific joint of the body creates the inflecion point.
