mination Paper 2016 Pag Which of the following is the best definition of elaborating a design specification? a. Elaborating a design specification involves changing quantitative requirements into qualitative requirements. b. Elaborating a design specification involves identifying the essential problems and the establishment of function structures. c. Elaborating a design specification is a part of the concept design process. d. Elaborating a design specification means enhancing the specification to make sure that all important criteria are covered. In which of the following projection systems is the shape shown in Figure 1 drawn?

Solution

A) Elaborating a design specification means enhancing the specificaion to make sure that all important criteria are covered.

Reason: Definition of Design Specification is as follows :

A design specification is a detailed document providing information about the characteristics of a project to set criteria the developers will need to meet.

For example, a design specification must include all necessary drawings, dimensions, environmental factors, ergonomic factors, aesthetic factors, cost, maintenance that will be needed, quality, safety, documentation and description.

B) It is an instruction to assemble, is usually drawn in isomatric projection and does not usually contain dimension

A complete assembly drawing is presentation of the product or structure put together, showing all parts in their operational positions. The seperate parts come to the assembly department after their manufacturing processes are finssihed and in this department they are put together according the assembly drawings. Small machining operations may be necessary during assembly process such as drilling, reaming, or hand finishing. For such cases, assembly drawings include a note explaining the required operation and give the dimensions for the alignment or location of the pieces only.

C) Bearing is a part where you can not tolerate any vibration or any misalignment. for that purpose we need to do precision machining at where bearing is going to fit and where bracket is going to be fitted. So, No need to do precise machinig at which parts whoes are only made a part of the assembly.

So,Outline shape of the bracket is probably produced by milling is not true because it will rise unnecessary production cost.
