4. FOUR BAR MECHANISM
A four bar linkage is also called “A four bar”.
It is the simplest movable closed chained linkage.
It consist of four bodies.
These bodies are called bars and links.
Generally link moves in parallel planes.

8. MAJORITY AREAS COVERED

9. DESIGN FOR MANUFACTURE
• The project has been designed mainly for vehicle purposes
• it uses basic parts which are described previously
• The parts for example nuts and bolts are the cheapest but they corrode overtime
due to continuous environmental changes.
• The mechanical mechanisms life depends upon the usage and the material used.
• The project uses Mild steel hollow rods .

10. COST AND USAGE
• The Production of the project mainly depends upon the materials used.
• The materials we have used are the cheapest available in current market
• The product Life is fairly enough
• Due to low cost the spare parts are easily available and can be manufactured in a
very short time at a low expense.
