Compression: it is the opposite of traction when an object that you tried to Crush or compress, such as a cloud of sugar or the legs of a chair.
Flexion: is when, for example the
shelves  when the books that weigh tend to bend and also flexion has efforts the traction and compression.  Torsion: is when you twist an object as for example sponge.

  • Tensile: In this image you see a stretched bracelet
  • Compressive: In this image you see a stopper crushed  
  • Flexural: In this image you see a flexed paper 
  • Torsional: In this image it looks like a shirt os crooked 
  • Cutting: In this image you see how the paper os cut on one side from above and on the other side from below

    Mechanisms; They are those that allow the movement of objects. They are elements designed to transmit and transform forces and movements of a motor element to a receiving element.
    Lever: it is in equilibrium when the product of the force due to its distance from the point of support is equal to the product of the resistance due to its distance from the point of support.

    Type of lever: It has two types of lever are first genre and third genre.
    —First genre: The first genre is when the fulcrum (point of support) is found between the resistance and the force. In the nail clipper would in the handle (upper part).
    —Third genre: The third genre is when the fulcrum is found at one extreme, the resistance in the other extreme and the force between both. In the nail clipper would in the cutting sheets the resistance, the force is where we make the force and fulcrum at the end.

    Type of lever: The construction crane is of first genre.

    -First genre: The point of support of the crane is between the resistance and the power.
    -A crane is a machine designed to lift and distribute loads in space suspended from a hook.

    -third gender: the point of support is at one end, the resistance is at the extreme end, and it is the power that lies between

    -description: the tweezers are used to pick up objects, but they are especially used to catch food such as: sweets, cut tomatoes, cut lettuce, striped cheese

    The first genre is when the fulcrum is a found between resistance and the force .In the prunning shears the resistance is the blades,the fulcrum in the midadle screw.

It's a pinion or a cogwheel with straight teeth., crimped to a zipper, that is to say, a belt or toothed bar. When the gear wheel rotates, the zipper moves with rectilinear movement.

Consists of a projection that is inserted into the base of the plate of the bottle as a wedge and a handle with which a lever action is exerted to remove it.

Its operation is due to gears and mechanisms that make the clock hands. The gears are divided into three parts
    1 Three gears are responsible for accumulating the energy to send them later to another gear
    2 Three other gears turn due to the energy transmitted by the first three gears
    3 The last two gears cause the hands of the clock to rotate properly as a pause of 1 second for each movement
