MY KNOWLEDGE ABOUT MECHANISMS

Hi!

Today I will explain you about mechanisms.

What is a simple machine?

A simple machine is a device that makes work easier by magnifying or changing the direction of a force

There are six types of simple mechanisms:

      -Lever: is one of the most basic forms of a machine. Its helps us lift loads with less effort.

      -Wheel and axle: a wheel is located to a central axle and they rotate each other when a force is applied on either one of them.

      -Pulley: a basic pulley comprises of a wheel on a fixed axle, with a groove along the edge to guide a rope

      -Inclined plane: it is a plane surface, set at an angle against a horizontal surface

      -Wedge: is made up of two inclined planes. These planes meet and form a sharp edge.

      -Screw: has a long and thin metal shaft with threads spiralling along its length.
This is an example where shows that we use simple machines in our dily life

TRANSIMISSION OF MECHANISMS:
There are four types of motion:
 
     -Linear motion:moving one way in a straight line

     








     -Reciprocating motion: moving backwards and fowards in a straight line

 

     -Oscillating motion: moving backwards and fowards in an arc

     -Rotary motion: moving in a cicle




CAMS:
     -Circular cams:















     -Snail cam
 

      -Four-lobed cam




 

   


  -Pear cam
