ME 4000           Project & Thesis

3 hours/week      Credits : 1.50

 

Experimental and theoretical investigation of various topics in Mechanical Engineering. The topic should provide an opportunity for the student to develop initiative, creative ability and Engineering judgement. The work may be done individually or in a group (Preferably not more than two in a group). Towards the end of the final semester; the students will have to submit thesis to the department.
