PROJECT WORK (Phase-I) Course code: Semester 5th Total Period: 60 Examination : - Theory periods: 4P / week Sessional Marks 25 TOTAL Marks 25 RATIONALE Students’ Project Work aims at developing innovative skills in the students whereby they apply the knowledge and skills gained through the course covered in many subjects and Labs, by undertaking a project. The prime emphasis of the project work is to understand and apply the basic knowledge of the principles of mechanical engineering practices in real life situations, so as to participate and manage a large mechanical engineering projects in future. Entire Project shall spread over 5th and 6th Semester. Part of the Project covered in 5th Semester shall be named as Project Phase-I and balance portion to be covered in 6th Semester shall be named as Project Phase-II. OBJECTIVES After undergoing the Project Work, the student will be able to:  Implement the theoretical and practical knowledge and skills gained through various subjects/courses into an application suitable for a real life working environment, preferably in an industrial environment.  Develop working models or applications and implement these for the actual needs of the community/industry.  Explain the working of industrial environment and its work ethics.  Explain what entrepreneurship is and how to become an entrepreneur.  Identify and contrast gap between the technological knowledge acquired through curriculum and the actual industrial need and to compensate it by acquiring additional knowledge as required.  Carry out cooperative learning through synchronous guided discussions within the class in key areas, asynchronous document sharing and discussions, as well as prepare collaborative edition of the final project report.  Find latest ideas on robotics, automation and mechatronics based projects. General Guidelines The individual students have different aptitudes and strengths and also areas of interest. Project work, therefore, should match the strengths and interest of the students. For this purpose, students should be asked to identify the type of project work, they would like to execute. The activity of problem identification should begin well in advance (right from beginning of 5th semester). Students should be allotted a problem of interest to him/her as a project work. It is also essential that the faculty of the respective department may have a brainstorming session to identify suitable project assignments for their students. The project assignment can be individual assignment or a group assignment. Preferably there should not be more than 5 students, if the project work is given to a group. The project work identified in collaboration with industry should be preferred. Following are the broad suggestive areas of project work  Automobile based projects.  Refrigeration based &Air conditioning based projects.  Hydraulic control &Pneumatic control based automation projects  Fabrication based projects.  Wind mill  Solar energy based projects.  Thermal power plant using steam.  Hydel power dam.  Cooling tower.   Solenoid based hammer.  Unmanned railway crossing.  Engine based air compressor.  Mobile all round year air conditioner  Driverless car.  Hybrid motorbike.  Any other areas found suitable.  Torque testing machine.  Spring testing machine.  Mechanical sanitizer.  Solar powered refrigerator.  Door opener. A suggestive criterion for assessing student performance by the external (preferably person from industry) and internal (teacher) examiner is given in table below: Sl. No. Performance Criteria 1.
