What is the first step of design procedure?
Discovery is the first step of the design process, where teams work together to develop an understanding of the problem they are trying to solve, and define the path they will take to explore solutions. It culminates in the communication of a vision – a concise mantra of the team’s conclusion.
How will you classify machine design and explain it?
This is where the fundamentals of machine design come in, and they can be broken down into three categories, Adaptive Design, Developmental Design and New Design .
What is general considerations in design?
Selection of Materials It is necessary to a designer must have a thorough information of properties of materials and their behaviour under functioning conditions, various of main characteristics of materials are: strength, flexibility, durability , weight, resistance to heat and corrosion, capability to cast, welded or ...
How do you choose the right material?
- Function – what we need this product to do.
- Durability – the product should stand the test of time.
- Aesthetics – the fine balance between appearance, durability and cost.
- Consistency of performance – the product should record a low failure rate in testing.
What is the material selection process?
Material selection is the act of choosing the material best suited to achieve the requirements of a given application . Many different factors go into determining the selection requirements, such as mechanical properties, chemical properties, physical properties, electrical properties and cost.
What is material selection chart?
Materials selection charts are used to screen out materials which do not meet the design constraints , and materials indices are used for ranking the shortlisted materials in order of excellence.
