Suggested Micro-Projects
Only one micro-project is planned to be undertaken by a student that needs to be assigned to him/her in the beginning of the semester. In the first four semesters, the micro-project are group-based. However, in the fifth and sixth semesters, it should be preferably be /7/r7zvz7/ff//jundertaken to build up the skill and confidence in every student to become problem solver so that s/he contributes to the projects of the industry. In special situations where groups have to be formed for micro-projects, the number of students in the group should not exceed three.
The micro-project could be industry application based, internet-based, workshopbased, laboratory-based or field-based. Each micro-project should encompass two or more COs which are in fact, an integration of PrOs, UOs and ADOs. Each student will have to maintain dated work diary consisting of individual contribution in the project work and give a seminar presentation of it before submission. The total duration of the micro-project should not be less than 16 (sixteen) student engagement hours during the course. The student ought to submit micro-project by the end of the semester to develop the industry oriented COs.
A suggestive list of micro-projects are given here. Similar micro-projects could be added by the concerned faculty:
- Take any day to day life component, find load, stresses and also prepare chart/model for the same.
- Make models of various joints and levers highlight resisting sections of different elements.
- Make models of various shafts, keys and pulleys highlight resisting sections.
- Make models of various couplings highlight resisting sections of different elements.
- Make chart indicating different thread profile and sizes required for different loads in case of screwjack, toggle jack, C-clamps and lead screw of machines.
- Prepare model of eccentrically loaded bolted and welded joint and highlight the maximum loaded section.
- Prepare list of different types of bearings used in a bike and write their specifications and basis for selection.
- Prepare list of different types of Gears used in Agriculture machinery, Sugar can juice machine, gear boxes of two and three wheelers and similar machines, write their specifications and basis for selection.
- Prepare list of different types of levers and springs used in a bike, Rickshaw. Moped and write their specifications and basis for selection.
