1	Automotive Design
2	The Design Purpose: A machine or machine member is usually designed to perform its function for a specific length of time without failure.
3	The Design Process: Recognition of Need Definition of Problem Synthesis Analysis Optimization Evaluation
4	Design Considerations Strength Reliability Thermal Properties Corrosion Wear Friction Processing Utility Cost Safety Weight Life Noise Styling Shape Size Flexibility Control Stiffness Surface finish Lubrication Maintenance Volume Liability
5	Codes and Standards Standard is a set of specifications for parts, materials, or processes intended to achieve uniformity. Code is a set of specifications for the analysis, design, manufacture, and construction of something. The purpose of a code is to achieve a specified degree of safety, efficiency, and performance or quality.
6	Types of Forces (Loads) Concentrated Load Distributed Load Steady Load of Constant Value (Static) Variable Value (Dynamic) Gradual Load Sudden Load Repeated Load Reversed Load
7	Unit of Force Newton (N) is the unit of force. One Newton is defined as the amount of force required to give a 1-kg mass an acceleration of 1 m/s/s. 1 N = 1 kg x 1 m/s²= 1 kg m/s² The weight of 1 kg = 9.81 N (w = m x g) kilo newton (kN) = 1,000 N = 10³N mega newton (MN) = 1,000,000 N = 10⁶ N giga newton (GN) = 1,000,000,000 N = 10⁹ N
8	Working Stress and Factor of Safety: A motor vehicle component must not be stressed beyond the allowable safe working stress and that must be below the elastic limit of the material. The choice of a suitable factor of safety depends very much upon the physical properties of the material employed and upon the nature of the loading. When deciding what factor of safety to use, factors such as corrosion, expected life of the component, possibility of mishandling, etc.
