Structures and
mechanisms
- Structures
- A structure is a set
of elements of an
object that allow it to
maintains its shape
and size without
defaming when
forces act on it.
- Types of structures
- Naturals:they are
structures made by
nature,for example the
queleto of the animals,
etc...
Arti-fical:structures
which are all
manmate,for example a
house, etc...

- Types of structures
- Elements of a structure
- .Beam or
catiliver
.Column
.Brace
.Square

- It is very
important that
the structures
are stable and

- Mechanisms
- A machanisms
is an element
that serves to
facilitate
human work.A
machine is
made up of
several
mechanisms.
- .The wedge:is a simple
machine that is used to
separarte bodies. .Inclinated
plane: allows you to raise or
lower objects with less
efforts. .The screw: allows
man to lift loads continuously
with little effort. .The lathe:
consists of a cylinder that
rotates by means of a crank.
.The pulley: is a grooved wheel
through which we pass a
rope.

- Motion transmission
mechanisms
- The machanisms of
transmission of
movement are
elements that
transmit the
movement without
transforming.We
found 3 types:The
friction wheels,The
gears or sprockets
and the pulley-belt
assembly.
- Multiplication and reduction of speed
- Depending on the
size of the wheels
or gears we will have
mechanisms that
multiply, maintain
constant or reduce
speed.

- Loads and efforts
- As we have
commented the
structures are
subject to
external forces
that we will call
charges.There is
2 types:
- .Stactic
load:Are those
that act
permanently on
a structure.
- .Dynamic loads: these are those that do
not act in a constant way on the
structures.There is 5
types:traction,compression,bendinng,torsion
and
shearing
or
cutting.
