i) Illustrate the Engineering Design Process with a slow chart commencing from Identification of Need to ending at testing a prototype model.
ii) Briefly explain each step involved in the process. You may use examples, if necessary. It is necessary that you include any activities under each stage.
iii) If you are assigned to design a mousetrap with the intention to market it, how would you proceed to work aligned with the above illustrated design process?
iv) What is meant by product specifications?
v) What are basic requirements of machine elements?
vi) What is Design Synthesis in machine design?
vii) What are Standards and Codes in Machine Design?
viii) What is interchangeability? With interchangeability being in practice, what advantages are expected?
ix) What are the five Basic Series (Renard Series) of Preferred Numbers?
x) What are the derived series from Basic Series of preferred numbers?
xi) A manufacturer intends starting a new business venture to manufacture and sell five different models of electrical power generators, capacities ranging from 7.5 kW to 75 kW. Specify the power capacities of the models.
xii) There is an expansion plan to further increase the above range from five to nine models to fulfill the requirement of users. Specify the power capacities of additional models.
xiii) What are the two main considerations on which the designer should focused at the design stage of a product?
xiv) What are the Properties of Engineering Materials, which are of major concern in machine design?
xv) Briefly explain Tolerance and Fit in component assembly.
xvi) What are the three different types of fits? Illustrate them in diagrammes. Give examples to each fit.
xvii) The power transmitted by V-belts is more than flat belts for the same coefficient of friction, arc of contact (angle of lap) and allowable tension in the belt. Explain this statement.
