Introduction to graphical
The purpose of graphics
Drawing is the most common and effective way to communicate and test design ideas
Drawing conventions
Two-dimensional drawing provides a way of drawing a number of views of an object.
Three-dimensional drawings allow us to represent an object as our eye normally sees it
Sketching
Oblique drawings use a square grid. Remember that the measurements placed on the 45 degree axis have to be halved
Working drawings
Single vanishing-point perspective drawings use
a square grid, but employ a horizon line and a vanishing point
Graphic techniques
Colour, texture and shading can be added to drawings to make the images look real. Colour can also be used to code and identify parts of drawings3

Levers and linkages
The levers in a linkage are connected at fixed or moving pivots. Linkages are used to change the direction of and movement
Second class lever
In the second class lever the load is always in the middle of the fulcrum and the effort
-
Mechanical system and control
the mechanical system basically control the object like hydraulics for the jaws of life
First class levers
In a first class lever the fulcrum is always in the middle and the load and effort is on the sides
Impact of technology
The impact of technology is massive like technology saves lives for example the jaws of life can get some one out of a dangerous situation quicker
Design skills
Before you make you have to design and there is a design process which consists of the following components: investigate, design, make, evaluate and communicate
Third class lever
In third class lever the effort is always in the middle of the fulcrum and the load
Levers and mechanical advantage
A lever a mechanical system that helps us to lift, push or pull things more easily we also call it mechanical advantage in levers there is also always these three things a fulcrum, the load and the effort
