For all other repair & maintenance 5th sem bteup diploma syllabus 2017 you can visit Repair & Maintenance 5th Sem BTEUP Diploma Syllabus 2017 Subjects. The detail syllabus for design & estimation practicals (for all groups) is as follows.
Rationale:
Designing is a creative activity. It requires coordiantion of various aspect of engineering knowledge. So it provides the students an opportunity to utilise their learning. Estiamtion is a process of deciding the production cost and material requirements. When coupled together it offers a self sufficient base for manufacturing. The paper aims to develop such capacity in the student.
NOTE:
- Treatment of the subject is limited to elementary situations only.
- Standard data required for the design problems are to be given in the question paper.
